One of the best old school FPS shooters in the late 1990's with a great OST. It also supports co-op natively.

Yes there are anime girls. But this game is quite fun, addicting and kinda difficult lol. Also the OST is great x3

Fun multiplayer Speedrunning game for up to 4 players. You may find that people say it's impossible to play with over 80 ping, but it IS possible!

Very good indie FPS shooter with double jumps, dodging and wall dodging in the likes of UT2004 and isn't COD! Very fun. Highly recommended.

Decent little platformer, which can get fairly difficult at times. Pretty levels. It has a great soundtrack, too.

If you're a Heretic fan, then you will probably like this too.

Very good Sonic racing game for PC which requires lots of practise to "get up there". If you liked Crash Team Racing, you'll probably like this too.

This is a great Platforming game which started off as a Sonic fan game. It's fun. It has a story. It's speedrunable. Top-notch Soundtrack & more.
