I am not a professional. These guidelines come from my personal experience of only 10 hours of gameplay and youtube videos I have watched. Everything may not be accurate. Use this guide as a foundation, upon which to build your own opinion. I made this in like 10 minutes.

The map is comprised of three areas each with their own objective.

The first area requires you to find 3 keys to unlock the exit.

The second area requires you to find a security officer zombie with a key card, usually found further in the level. Then you must use the key card to activate 3 terminals throughout the level. The three terminals can be anywhere within the level, including the very first room at the start.

The third area requires you to destroy 3 Bio Canisters. Keep your eyes high, the locations of the canisters glow in an unmistakable bright light but are often located at a higher elevation than the ground floor.

- Always buy flash grenades whenever you can, you will need them to defend against Mr. X
- Always kill yellow Supply Zombies, they sometimes drop powerful weapons such as miniguns or grenade launchers
- When making your way to the exit of a section, do not waste time fighting enemies that are not in your way, shoot or melee them to stun them, then pass by them

- Learn where the 3 keys can be. The area isn't very big.
- An easy to miss key spot is on the blue barrels in the corner of the first area before you even enter the building

- Purchase all the flashbangs you can for when Mr. X shows up
- Purchase a grenade to easily deal a lot of damage and knock over the security zombie with the key card(or be Tyrone and use his "E" ability to knock the security zombie on his ass and pummel him while he's down)
- Do not fight Mr. X, use a flashbang to stun him if you need to get by him, otherwise, just kite him by running around
-Mr. X cannot enter safe rooms and it may be a better alternative to wait in the safe room for him to despawn
- Complete objectives while Mr. X is focused on chasing other players
- One of the easy to miss potential terminals is in the same large room as the spawn

- Look up to find the bio canisters, most of them are at a higher elevation
- Melee weapons are very effective for destroying bio canisters
- The lift on the right has a switch at ground level to lower and raise it
- Look up and look in the distance to determine where the catwalks and lifts make pathways so you can learn to navigate the space more easily
- One of the bio canisters is tucked around a corner right in front of the exit
- Always determine where the current bio canister is so you can help your team clear the path and defend the area so the canisters can be destroyed.
- Do not run off because you are lost, if you don't know where you're going stick with someone else

Valerie is a support character who can heal everyone with her Fever Skill and can highlight all nearby items, through walls.

- Make sure you use your "E" Ability continuously whenever it becomes available to help everyone find the objectives
- Save your Fever Skill for a pinch where many players are hurt

Tyrone is the ultimate Chad and can take down every enemy with ease.

- Use your "E" Ability on priority targets ASAP. The "E" ability will knock enemies flat on their ass allowing all players to curb stomp them out of existence while they are on the floor. Priority targets include: Red Glowing Zombies or Player Controlled Zombies and Lickers. Tyrone's E ability only has a 9 second cool down so use it every opportunity you see.
- Buy the stronger melee weapons as soon as you can (Steel Bat, then Sledgehammer)

January is a hacker who's primary focus should always be camera management

- Purchase the Quick Draw pistol and ammo ASAP for shooting out cameras(January does more damage to cameras than everyone else)
- Always be looking for cameras, you must be able to anticipate when a teammate could start getting shot by a camera turret
- When entering spaces with long sight lines (ex. a hallway) make sure to disable cameras to avoid being easy targets for camera turrets
- Use your "E" ability to save ammo on destroying cameras
- If a turret camera is activated and your team takes cover, see if you can get the button prompt to hack the camera from around the corner without exposing yourself
- A good time to use her Fever Skill is immediately after Mr. X departs. Credit to Kally D.

Ok, after using Samuel numerous times and exclusively using his fists, he is still a weird ♥♥♥♥♥♥♥ dude. BUT he is also an absolute CHAD when it comes to damage.

- Samuel's "E" ability has a TWO SECOND cooldown, so always use it.
- Spam Samuel's "E" ability. Space yourself properly from your target because Samuel will dash forward when you press "E". Mash Left Mouse Button to continue attacking
- Melee combat is messy. Keep your target centered with your camera, otherwise you will miss all your attacks
- When your target falls to the ground or you begin missing, stop pressing Left Mouse Button so that you don't waste actions attacking nothing. Center your target with your camera, press "E" again to activate the skill again, and follow up with punches again
Samuel's Fever Skill has a cooldown of 2 minutes, which is reduced to 1 minute and 30 seconds after you kill 10 enemies. So also spam his Fever Skill

I made this because I'm getting sick of playing with people with their head up their ass. And I'm not an expert on this subject. Maybe this will help a few people out, maybe it won't. Oh well. Hope it helps you a little at least.
