This game has recieved very little recognition from almost anyone, but it really seems very promising (in beta). The game I'm talking about is Nether, a mmo survival sandbox much like DayZ, but the zombies aren't zombies, they're creatures that have multiple different types and abilities. Then of coarse there's PvP as well. The game takes place entirely inside of city streets which I think is pretty badass along with the fact that tons of the buildings are accessible. This might look like another WarZ, but I have very high hopes for it. Anyway, it's on Steam for 30 dollars or so in beta.
PS: CheatEngine doesn't work on it, so it's at least slightly more secure than COD Ghost
