To access Evrima:
Steam Library > The Isle > Properties > Betas > Beta Participation > Evrima

Launch game > Choose a server (official or unofficial) >

Before choosing your dinosaur, you’ll see two optional choices:
- Join via egg (if a public nest is open or you have a nest code)
- Spawn at a friend (if they give you the spawn code)

You can skip these and just continue with:
> Carnivore > Pteranodon > Choose color, pattern and gender > Confirm to spawn

You currently can't choose your spawn location. Its either West Access or around the Dam Lake.



The game has no in-game map, but you can copy your coordinates (TAB > top right) and paste it in one of these websites:

Other than your current location they also have many interesting features such as:

• What biome, lake, or structure you're near and their names
  
• Where freshwater sources, gastroliths, mud patches and salt rocks are
  
• Locations of sanctuaries, migration and patrol zones
  
• Where AI animals are more likely to spawn

Default keybindings


Airbrake (Z): I recommend rebinding it to something more convenient (I use Mouse 5). It really improves maneuverability.

Press X to toggle night vision.

Its effectiveness varies by species and weather conditions. On very dark nights, even night vision might not help much. You can improve visibility greatly through your system settings:

• Windows Key > search "calibrate" > Calibrate Display Color
  
• next, next, next
  
• set the scale to maximum

Pteras have pretty good stamina, they can fly and glide for a long time.
But they have horrible stamina regen. It takes about 4-5 minutes. So focus on preserving it.

• Basic takeoff: 6–8% stamina use, tap SPACE 3 times: jump, flap, start flying
  
  Reinforced tendons mutation: Jumping costs less stamina. Unlock by jumping 50 times.
  
  
• From higher ground (rock/tree): 0% stamina use. Sprint/walk/fall off, tap SPACE in mid-air
  
  
• From latched position: 0% stamina use, tap SPACE

You can save yourself from falling to your death with Tap SPACE:




To land slow down by holding Z (or the rebinded key) and aim your camera at your landing spot. For a quicker descent hold Z+W or Z+CTRL. To latch hold Z+RMB. Hold them until you touch down. If you release Z without enough speed, you'll stall and fall straight down.




How to: Take off then aim slowly upwards while holding W until your wings begin flapping.

This video is sped up 16x. The upward climb (holding W) took 3m35s, and the glide lasted 8m, for a total of 11m35s. The wing flaps during the glide are part of the animation, no input was used.

• To reach very high places like the Highlands, hold SHIFT + SPACE to gain as much altitude as possible. Once you're up, glide to a ledge or surface at that height and rest (H) to regenerate stamina for 4m12s, then fly to your destination. Use thermals if they’re active and along the way.
  
  
• Generally try to not use SHIFT (for speedgain) or hold SPACE, as they consume a lot of stamina.
  
  
• Go around hills / mountains / rocks (not over them) to preserve stamina. Use tunnels.
  
  
• Sync SPACE taps with the wings downward flap to use stamina more efficiently while flying.
  
  
• Stamina regenerates while latched if you're above 20%, or while standing if above 25%.
  
  
• You can’t latch if you have 0% stamina.
  
  
• You can still take off when Wounded, but not with Fractured Legs.
  
  
• Sadly pteras can not dive into or take off from water, so try not to fall in. Swimming out consumes a lot of stamina, and in large bodies of water you will probably drown.
  
  
• Zoom in with the middle mouse wheel for tighter camera control. It helps a lot when flying through dense forests, almost like switching to first-person mode.
  
  
• Using RMB while latched will drop you straight down.
  
  
• Perfect diet increases stamina regen.
  
  
• Dont be afraid of flying close to objects. Lets say there is a herrera on that tree.

that gives diet





Always smell (Q) food before eating to see if it's safe and nutritious for you. Diets show up as: If it shows the meat icon or chunk of meat icon it’s not your diet or rotten. Eating non-diet food fills your stomach but gives no nutrients (and no perks). Eating rotten food will make you sick and vomit.

Examples:

Diet → Rotten corpse







Diet → Rotten chunk







Not diet

(This chart does not account for AI spawn inconsistencies caused by current game design.)


Fish – Amazing food. Best and easiest, if they spawn. (All fish, big or small, provide the same amount.)

Pterodactylus (bird) – Fills a full stomach for a freshspawn. By 25% growth it only fills half and for adults just a small portion. To spawn them fly around carrying meat. (Note: You can’t attack / bait / eat the loud birds near huge trees.)

Crabs – Good while staying at coastal areas and need ,’, diet. If they spawn and you can find them. They’re tiny.

Frogs – Adults can bite them from the water. As a freshspawn, you’ll need multiple hits, then dive in, grab it, and swim out to eat. If it goes on land, it’s almost impossible to catch due to dodging and jumping.

Rabbits – Probably the hardest AI to kill. Small, fast, and dodgy. At least they fill your stomach well.

Chickens – Spawn in all land biomes, making them reliable. Follow the call and land a few meters away to let them run to you. Adults one-hit them. Freshspawns need several hits, and chickens will fight back, causing bleeding. If not killed quickly, they run/fly away.

Turtles – Great for a large ptera family. But as a freshspawn alone, they take about 4 minutes of constant pecking. Even adults need a few hits. Use ALT+LMB on the ground for higher damage.

Psittacos (taco) – Loud and slow, but easily lost in bushes. They spawn near their burrow and stay close to it. Even adults need multiple hits.

Other pteras are not part of your diet.


Perks of having nutrients = perfect diet










Diet types
Stay near the biomes where your needed diet spawns. Stick to water for fish and frogs, beaches for turtles. Be stationary for a while, then fly around to sweep the area. They often spawn nearby.
(This is recommended when you are going for perfect diet, not when you are starving.)

Slower nutrition decay
Enhanced Digestion is a hidden mutation that causes your nutrition bars to drain 10% slower.
You can unlock it by maintaining a good diet (or better) for a long time. Check for this mutation after 75% growth.

After spawning
You have 14 minutes before starvation begins (while still having 60% water) and 11 more minutes until death. Choosing the Efficient Digestion mutation (20% slower hunger) adds only 4 more minutes.

Upon spawning stand still and Hold Q for 20 seconds to smell around for food. This gives max scent range. If you see a meat icon, go there but don't eat it, just grab a chunk (G) and fly to spawn birds. (Also less likely to get eaten by what killed the corpse.) When birds appear, drop the meat, land, attack, eat.

Repeat until you find fish, frogs, crabs, or benefit from older pteras or other dinos killing bigger AI. You can try killing AI yourself, but it’ll take time.

Just by baiting and eating 3 birds, you can already reach your second mutation, without needing to drink even once.


Ai don’t spawn everywhere. They have specific spots you’ll learn over time with map knowledge. If no meat is nearby after smelling, here are some recommended routes and areas:



From West access spawn

• Head south to Mudflats. Often full of turtles and players. The grassy northern side sometimes has chickens or rabbits. In the Southern Plains, the river rarely has fish, but the Saltlake waterfall often has bugged fish stuck at the bottom. Tacos, chickens, and rabbits can also be found nearby. High player activity, frequent fights, and plenty of corpses. Both areas are close to sanctuaries. If you dont have saltwater mutation, drink from the savanna ponds.
  
  
• Head east, behind the human base. Go around the terrain (not over) to preserve stamina. The lower hillside is full of chickens and rabbits. Hunting skill on hilly terrain required. The upper lake may have fish. With bird baiting, you will have perfect diet quickly. Few to no players in the area.

From Water access spawn (check the Dam Lake for fish)

• Head southwest, up to Highlands. Lots of chickens, rabbits, and occasional fish at the lake. Medium to high player activity. Watch for crocs. Drink from shallow parts of the lake or from logs.
  
  
• Follow the river down to Delta. The northern side often spawns fish due to proximity to a sanctuary. The southern side has many chickens and rabbits. Beware of crocs. Moderate player activity. (Beipis like to nest on the island east of Delta, south of Coastal Pond.)
  
  
• Head northeast, toward the small fenced area near the salt spot. Wait top of the saltrock to spawn chickens and rabbits along the road in the open field and in the jungle. Fly east to reach North Lake. It may have good fish spawns, but watch out for crocs. Drink from shallow parts of the lake or from logs. Low player activity overall.

• LISTEN more than look. Learn the audio cues (some are player dino calls, some are ai calls and some are ambient sfx that means nothing). The frog and chicken are obvious. The fish splashes. The crab digs the sand. The psittaco makes a very unique sound that can be heard from quite far. Bushes also rustle if animals run through them.
  
  
• AI spawns increase near more players. If you hear other dinos, you're close enough to benefit. (Potentially you get to eat their corpses or use their meat to bait birds)
  
  
• Fly low (under the tree canopy but above the bushes) to force AI to move, making them easier to hear or spot. Then drive them out of dense forests or bushes into open, flat areas like fields, rocks, or beaches. Always hunt downhill to preserve stamina.
  
  
• Adult pteras can carry crabs, frogs, rabbits and chickens. Tap G to pick up a chunk of meat, Hold G to pick up the whole animal.
  
  
• Eat and drink with over 25% stamina to allow regeneration.
  
  
• Eating none diet corpses means no nutrients = poor diet, reduced growth and infertility.
  
  
• Accept that you will starve to death a few times before you have enough map knowledge of the best ai spots.
  
  
• If you are new to the game or playing ptera consider joining unofficial servers with more ai and shorter growth to get a feel of the game.

Getting water is easy, just fly until you find a safe spot to drink. Ponds (small or at edge of the map) and larger bodies of water are usually safer. You can drink from the tops of logs sticking out of lakes or from areas where water clips through the ground.

Reniculate Kidneys (hidden mutation)

This lets you drink saltwater. Unlock it by drinking saltwater until the "Fluid Deficient" status disappears. Do it near plenty of food and water to recover quickly after vomiting.

Eating rotten food, drinking saltwater or getting poisoned causes vomit sickness, which prevents nutrient gain. To recover, lick salt. Look for pink crystals at the base of rocks. 25 salt spots exist on the map, these locations can be found on the maps.

Small patches found all over the map. Pecking one drains your stomach slightly. They are useful when you want more diet quickly, but have a full stomach. The effect only lasts 1 minute and shows up as “Ingesting Gastrolith” on TAB. Peck again to refresh it.

Every player gets to choose 3 mutations as they grow, unlocked at:

• 14% growth – first mutation (when you spawn)
  
• 39% growth – second mutation (about 30m of gameplay)
  
• 100% growth – third mutation (about 1h 25m of gameplay)

If you forget to choose one before the next unlock stage, you’ll miss out on that slot entirely.

If you nest and raise hatchlings, they will inherit 3 chosen mutations of the parents randomly and be able to pick 3 additional mutations of their own as they grow.

Full grown LMB attack: 20 dmg
Full grown ALT+LMB attack: 30 dmg

Practice attacking AI first to learn how low you need to fly to land a hit. The bite (LMB) has decent range, so you don’t need to dive in too close. Flying too low can make you collide with your target, causing a fall and likely death.

Learn sanctuary spots by using the map and hunt there for juvis. Pteras aren't attacked by bees.

• Hypsi: beaches, jungles. They can blind you.
  
• Troodon: beaches, grasslands, highlands. They have venom.
  
• Beipi: water biomes, highlands, jungles. They can make you bleed out fast.

Circle above and strike. Headshots deal the most damage, but they’re riskier since enemies may bite back. Fighting anything that can jump is not recommended, but if you choose, do it between jumps. Dont fight from the ground even as an adult, because pteras are weak.

Other pteras are not part of your diet (ptero, the bird is). Some players may still attack you. A full-grown ptera can one-shot another with ALT+LMB. Be cautious in the air, crashing into other pteras makes both of you fall.

You can shake off a Troodon if it pounces on you. Land and hold E.

Water is your enemy. Pteras can't take off from water. Falling in will drain stamina fast and in large bodies of water you’ll likely drown.

Fractures (broken legs) prevent takeoff. Wounded or bleeding does not stop you from flying.

Rest often latched to trees/rocks and heal far from the ground. Watch out for Herreras climbing to your resting spots.

Salt heals vomit sickness and poisoning.

• Group up with an opposite gender ptera.
  
• Court by holding N facing each other. (at least 70% grown)
  
• Once bonded, the female can gestate eggs (which slightly lowers her stomach)
  
• Information of the eggs and nest can be reached via TAB > NEST
  
• Eggs grow over time before they are ready to be laid.

Building the nest

• Choose a safe, elevated location (tree branch, rock, etc).
  
• Press N to place the nest.
  
• Gather 10 sticks: use Q to scent them, G to pick them up, E to add to the nest.
  
• After the nest is built, eggs can be laid by the female standing over the nest and holding E.
  
• Keep the eggs temperature stable. Sit on the nest to keep it warm, get off for cold.

Joining Settings

• Parents can set each egg’s privacy individually as:
  
  • Public: anyone can see and request to join
    
  • Private: joinable only with a code in the TAB > NEST menu
• When a player requests to hatch into an egg, a warning icon appears on the nest and an egg in the TAB > NEST menu.
  
• One parent must manually accept or decline the request by clicking on the specific egg.

Raising Hatchlings

• Hatchlings inherit 3 random mutations from the parents, then choose 3 more as they grow.
  
• Babies can’t eat regular food or drink water. They beg to be fed by holding E.
  
• Any adult ptera (over 70%) can feed babies by regurgitating directly into their mouths by holding E until they hear the baby swallowing.
  
• Begging ends at ~13.5% growth. This is also when they can fly for the first time.
  
• After that, hatchlings must eat regular food and drink water.

Additional Nest Info

• You can only have one nest at a time.
  
• There is a 5-minute cooldown before placing a new nest.
  
• Nests can be destroyed by attacking them.
  
• If one of the parents dies, no more eggs can be laid.
  
• If you want to pair up with someone else, a new nest must be made.
  
• Stick collection is known to be buggy.

Thermals: Warm air that lifts you up without using stamina.

• Found above huge rocks and have to be very close to see some particles flying upwards.
  
• Activation times varies (see picture)
  
• Not during heavy rain or storms.

Slipstreams: Wind that pushes you forward with little stamina use. Flying against slows you down and takes more effort.

• Found at tree canopy height and have to be very close to see some particles flying sideways.
  
• Active between 6:00 – 12:00
  
• Not during heavy rain or storms.

(These features have been mentioned, but nothing is guaranteed)

• Infrared vision
  
• New alt attack
  
• New flight mechanics
  
• Ability to spearfish or catch clams hiding under the mud that require breaking open on rocky surfaces.
  
• Canopy feeding and luring in different creatures to catch

Additionally

• Elder system with the 4th mutation. Growing old and dying of old age (which is initiated by the player and not automatic), and passing your mutations onto your next life.
  
• A new massive flying dinosaur (Quetzalcoatlus?)
  
• Baby turtles or turtle eggs
