This is survival game for one player and for cooperation in 4 players.

I want to make this game as "charity project" , as little help for Ukraine. Money from this project will be send to Ukraine.
Because I don't have a publisher yet for this project, 20% of our proceeds will be used for fees, taxes...
80% of our proceeds will be send to Ukraine.

The game now includes:
Single player with co-op for 4players - Host / Join sessions - hosted game, player characters, dynamic crosshairs, points system, spectating & respawn system, revive system.

In game is many achievements, group and individual. And game is connected on Steam statistics. Online leaderboards and other player statistics.

Game will have chapters and each chapter will have many maps. For player will be in maps side objectives like rescue infected civilians, find tags of lost soldiers....
Maps will not exactly corridor maps, maps will have little bit maze with many monsters for more fun.

I don't stick to real weapons in the game. It's not a real combat simulation. I want to make a fun game with different links to real places but still focus on gameplay.
