Killing Floor 2 is an extremely fun Zombie co-op shooter. The graphics are so pretty, the sounds are amazing and it has fun replayability with it's progression system. If you played KF1, 2 to me takes what made the first one so great and adds on to it. Def would recommend it.

One Finger Death Punch is a satisfying indie game. You basically use your mouse left and right button to fight off stick enemies but it gets so much more complex than that. Different speeds, enemies, and modifiers really make this game stand out. It might be stick figures but it's just so amazing how fast and fluid the game is.

Mark of the Ninja is one of the best stealth games I ever played besides Dishonored. In my opinion, it truly marks what makes a great stealth game. The level design is rock solid, the narrative and art style is beautiful and I love that it's a side-scrolling game! Really get this if you're a fan of excellent stealth games and if you're not, try it anyway!

Dust: An Elysian Tail is my favorite Metrovania. The game was developed by one person! Dust has a wonderful story behind it, and the voice acting is top notch. The levels and graphics are eye candy as well. I've yet to beat it but it's a game you can play from start to finish.
