Shootmania follows in the same style as Quake and Unreal Tournament but it's more modern

OP is asking for Shoot'em'ups not FPS.
You can find this on steam:
-Sine Mora
-Gundeadligne, Gundemonium Recollection, Hitogata Happa (This 3 are related)
-eXceed (another trilogy of games, i think a bundle is available. The 2nd is the best one, Ikaruga clone )
-Satazius ( Nemesis/Gradius style)
There are some more, and some remakes like Choplifter HD.
EDITED
Ether Vapor Remaster, a real good 1!

Thanks Raideoul those are exactly the kind of games I'm looking for! Does anyone know of more?

Jamestown is pretty cool. Jets 'n' Guns is up on Greenlight to vote for; I spent a ton of time playing that when I was in high school. Beat Hazard is fun, especially if you have intense music on your computer.
