The game name is "Project Elimination : Warmode" but you can call it only Warmode. It is an indie game (was not developed by a company) and it has a lot of potiential. Deserves a look ! It is a half life mod then the graphics are not the best. But apart from that the game is spectacular. It is like call of duty, and it needs no good hardware or like any online fps nowadays, has a shop and a inventory which not depends from the server it also has perks ! The game modes are demolition, deathmatch and zombies (At least is what i see in the servers). It has few guns but the developer will increase it. I think he's leaving the project because the game has no players. Then i came here with intention of help he. Would not like if a project like this fall down.
