New version, big changes!

It was decided to abandon the development of a multi-level singleplayer to improve existing mechanics, for convenience in general, and for the greater fun from playing.

• Now you can use both hands to shoot any weapons just by holding both shooting buttons.
  
• All weapons are now automatic. You don’t have to click all the time and traumatize your mouse or a gamepad.
  
• Reworked bullet spray system. Overheating doesn’t affect accuracy anymore.
  
• The crosshair now shows how big is spraying pattern while holding the shooting button.
  
• Reworked recoil system. If the player is standing still, then recoil is two times weaker.
  
• When picking up a new weapon, your previous one won’t drop anymore.
  
• Removed hit multiplier zones from enemies. Instead, a new critical hit system is added.
  
• Appropriate rebalance was made for weapons and perks.
  

• New vehicle - an invulnerable timed jeep. You can get it as a bonus after killing big zombies and bears.
  
• Getting into vehicles is now instant. All you need is to get close enough to jump inside automatically.
  
• Changes in vehicle and ramming physics. Hitting the crowd now feels a lot more pleasurable.
  
• The medkit will heal the player inside the vehicle, if that vehicle is already  at full health.
  

• Improved XBox 360 gamepad support.
  
• Removed buttons for slowmo, turning around, and leaving a vehicle.
  
• Gamepad buttons are now duplicated. D-Pad and a left stick are working in the same way, also “Back” and “Start” buttons now open pause menu.
  
• Removed “Keyboard only” movement controls. I’m sure, no one ever used it.
  
• Sadly, we had to remove keybind settings menu.
  

• “Zombie PacMan” and “Civil disorder” maps were changed. Mostly by adding more enemies.
  
• Changed player collision physics. Now you won’t jump off the enemies, instead, you will go right through them, pushing enemies away.
  
• Added appearance of the “W@ Games” logo when launching the game.
  
• Changed the effect of changing windows in menu.
  
• Volume window won’t appear after game start anymore.
  
• Removed scenario-based singleplayer.
  
• Removed all maps where you had to protect the right side of the screen. Now enemies on all levels will try to kill you and NPCs.
  

• Fixed enemies and other objects getting stuck behind map boards.
  
• Added ability to change the graphics driver. It will fix the bug that can break textures.
  
• Fixed a bug that allowed bears to heal from vehicle collision damage.
  
• Fixed shell cases flying two times higher than intended.
  
• Fixed upgrade points not being refunded when weapons were added by a cheat-menu.
  

• Added new parameter for vehicles "ShowHP" - it allows to show or hide the health bar of a vehicle.
  
• Added two new parameters for weapons: “CritChance” and “CritMultiplier”.
  
• Fixed reading of the last line in scenario files, Enemies.opt, and Vehicles.opt.
  
• Added new parameters for weapons: SprayNow, SprayMax, SprayPerShot, SprayCooldown. More info will be added in the manuals.
  
• Removed “Rules” map parameter. Now it’s always a survival.
  
• Added new weapon parameter "Recoil" - how strong is recoil after the shot.
  
• Temporarily removed the ability of adding hotkey buttons in texts.
  

I can say that this is an intermediate update. There will be further serious updates, changes, then polishing and, at last, an addition of online multiplayer.
