You can return into where you were at with the same gears.

There is 3 different difficulty levels:
People would say Easy, Normal, Hard but in reality i would say Easy, Hard, Expert

Crows will trigger hordes (alarm doors, Retch guts and Screamer can also trigger hordes)
They cannot be shot
Alarm doors are random, can be any doors.

An exemple in map2, when you go outside at some point close to the saferoom there is a crow nest (the one in pic below) then you will have an other one just few step after, add this a possible alarm door right after those nest and add the potential SI that call hordes (Snitch and Retch) you can have a combination of 5 horde trigger in one spot, isn't it completely useless?
EDIT for the text just above there is 6 crow nest and they ALL have chance to spawn!













Perfect bots when they use Grenades



















Rescue is one by one and it takes a little time like when you heal yourself.











You can actually open inventory and drop anything from it to share with teammates by clicking on it

• Bot (survivors) is worse than L4D2, most stupid AI possible.
  
• Bot throw molo and run inside it, also they can throw them on you
  
• Bot use Melee and Throwable (but badly) exemple they rush in hordes with melee and die
  
• Bot still play if you die, and you can control them anytime even tho you died
  
• Bot actually obey to you when you tell them to move (excellent thing) they also TP
  
• You can switch bot during game by going AFK
  
  
• SI wander around unlike L4D2 they do not always hunt you
  
• SI can't pin you untill death unlike L4D2
  
• All infected react to sound much more than L4D games
  
• You can not one shot SI with melee or any gun (maybe just snitch with shotgun)
  
• The same SI can spawn multiple times at once (max 2 apparently)
  
• It is really hard to rush through hordes with melee/bash
  
• Too much zombie too much hordes, no cooldown, no relax
  
  
• Movements are similar to Killing floor / Dying light (you can climb over stuff at your height)
  
• When survivors has no hp they get down only in CLASSIC (Surv and Nightmare = insta death)
  
• Using melee, bash, jumping and running consume stamina
  
• Some doors are locked, you mush break them with bash or melee
  
• Melee have all different damage, speed, swing (horizontal, vertical)
  
• Map is pretty good, similar to L4D2 ones with items spot (random spawn rate)
  
• You can carry only one heal item at once (kit OR pills + defib OR toolkit)
  
• You can find guns with attachements randomly
  
• There is different type of ammo (rifle, pistol, shotgun, sniper)
  
• You can find gold and items all over the map randomly
  
• If you die and get revived or respawn in next chapter you keep all your gear

First of all, create your deck.

You must choose 15 cards you will use as a deck ingame, you can create multiple different deck and edit them later.
1 card is Loadout (will be used all the time at the beginning) then you will have to choose between 3 random cards from your 15 cards.

First map you draw 3 cards
Each saferoom will grant you one more card
Each time you die will grant you one more card
You can find card ingame to grant temporary bonus

Each of them have differents abilities.

You have only 2 attempt, after then you restart whole campaign? (worst feature)

Each safe room has a box wich is a shop where you can buy throwable, heal, attachements, ammo, bonus.

This is how it look when you crouch with ALL guns

nothing different compared to l4d2 beside they do more damage and are slower


Basically boomer/spitter fusion with a similar range to the Spitter wich is insane.
Spit something that blind you a very little, and damage you at the same time plus it stay on ground for more damage, if it explose near you, you also get damaged and call a horde.


scream to gather horde, even when you kill them from far away without noticing you they do (wich is stupid) You have to avoid it or insta kill it with shotgun.


The hunter that spit some sort of web to stun you forever? (can be remove if a teammate bash you) the range is as big as the Retch.


The charger like, really tanky much stronger than charger probably the most dangerous SI actually


The gigantic useless infected (in the alpha version) (Grenade make really good amount of damage to him)
If you deal him 25% damage he just leave the map, you can also rush a bit to get into area he can't follow you.

Your inventory has 5 slots:
Secondary / melee
Primary
Throwable
Heal
Item
You can carry only 1 item per slot, by using cards you can increase the number of items in each slot (for exemple can carry 2 or 3 molo, 2 or 3 pills, 2 Primary weapons...)

Each guns and attachements have a stars rating from 1 to 4 that make them more or less good. Also they seem to have a color like the cards (green,red,yellow,blue) not sure why yet.

Machette (horizontal hit)
Bat (horizontal hit)
Axe (vertical hit)
Hatchet (vertical hit)
Knife(card only and replace bash)

Secondary
Glock
Pistol M1911
Magnum
Tac9

Primary
Uzi
870 Express (shotgun)
Tac14 (Short shotgun)
M1A (hunting rifle like)
AK47
M16 (3 shot at once similar to the SCAR in l4d2)
M4 Carabine
RPK (Act like the M60 in L4D2 but can be reloaded)

Molotov (the fire is really odd)
Grenade (explosion on impact)
Firework (Attract hordes but do no damage)

Bandage (heal 30 HP)
Pills (give temp health like L4D2)
Kit (heal 75 HP)

Defib
Ammo pack
Toolkit (to open special rooms with lot of items)

Some will help you others not (white and red colors ingame)

Reflex sight (reduce movement penalty when ADS)
ACOG scope (increase accuracy + increase damage to weak spot)
Laser sight (increase hipfire accuracy)
Extended Mag (increase magazine size)
Fast Mag (increase reload speed)

Long barrel (decrease maximum bullet spread)
Bent Barrel (increase maximum bullet spread)
AP ammo (increase bullet penetration power)
Heavy stock (decrease movement speed)
Heavy reflex sight (increase time to enter in/out ADS)
Short magazine (decrease ammo capacity)



Copper(gold)
Cards
Minigun (you can move it, available only on FINAL) the sound of it is bad but it's powerful.

I probably forget stuff, and i will update the guide if i can during the alpha time, you can also tell me what did i forgot.

You can send your opinion about the game in comments.

To me the game is ok tier, not worth 60$ at all (for now) especially they already have deluxe version and DLC (what kind of DLC? no one know) i hope i really hope it won't turn into a pay2win system..
Plus considering the fact that they make us pay for more content (maps and stuff) there won't be any workshops otherwise we could just reproduce the map for free. I guess it is far away from left4dead2.

Make a public BETA before full release please.

I was ready to buy the game even for 60€ to be honest but since I know there will be multiple DLC with new characters, infected and their own abilities I don't feel like playing a probably future unbalanced game (versus) with players who paid their monthly dlc and those who cannot. So for now I won't buy it.
