It consists of two modes, "Deathmatch" and "Zone Control" (each mode has its own fighting locations). Deathmatch features players fighting against one another, while Zone Control divides players into two teams: Shadowguns and Mutants. Each team must work to control the zones, until the opponent team controls nothing or until the other team has no more respawns left.
The game allows adding friends, whom you can invite to play against. There are also items, like guns, bombs, medical aids, etc. available for purchase in the menu.
