Zkiller

Zkiller is a first-person action game where you play as a survivor of the zombie apocalypse. Now, it's your job to fight against as many waves of zombies as you can by picking them off one by one. Luckily, you have a pretty solid arsenal at your disposal.

Gameplay in Zkiller is very simple. The game takes place in big but closed-off scenarios that you can explore freely, trying to kill the zombies that appear one after the other. When you kill the last zombie, you'll have a chance to recover a little and reload your weapons before the next wave comes.

The first time you play, all you'll have is a shotgun, pistol, and ax. As you beat levels, however, you can unlock tons of additional weapons, such as assault rifles, sawed-off shotguns, machine guns, machetes, and grenades. Another interesting aspect of this game is that the higher the difficulty at which you play, the more money you can earn to buy new weapons.

Zkiller is an excellent first-person shooter with non-stop action. Without much of a story or complex characters, this is still a fun game to play if all you want to do is kill zombies. The graphics are pretty good, too.
