Tired from playing same FPS? Want to try different type of shooter? This is the best fit!
It's easy to play and learning curve is few minutes. There is 40 or 50(patch) levels with tons of monsters, nice perks and plenty of weapons, which will make your bloody massacre successful!
There four type of game modes, quest - 40 levels, survival - stay alive as long as you can with all unlocked perks and weapons, rush -stay alive as long as you can with AK-47 and type'o shooter - write words to kill aliens with your shotgun!
I think this is the best game for one evening!
