18. Fantasy Strike. Some players did mention this game does remind them of the good old DOTA2 game; this game is that good! This one of those action-filled cross-platform games that center on one-on-one battles; safe to say this is a good graphic game that meets mixed martial arts.
12. Arizona Sunshine. Arizona Sunshine is a zombie shooter with a 4+ hour campaign and a wave-based horde mode to boot. Even better, both the campaign and the horde mode support multiplayer, so NumDDO.
