Download Operation Entity
Operation Entity is a pretty basic first person shooter game that will put you in a few missions that need to be solved in order to progress with the story further and be able to save the day. The game, however, has a bug that you will find annoying after a while: you cannot die and it is pretty weird to just walk by killing enemies without any problems at all.
The graphics, however, look rather nice, as they are modeled in three dimensions. In the game you will also have access to two different weapons, an AK-47 and a pistol.
