Ok... I admit... I'm a sucker for good old no frills shooters. But where are the truly awesome and great ones??? I have 2 installed currently and I would love to extend the amount a bit. I'm looking for flashy modern action here, so don't suggest old classics like RAPTOR or something else that would require a DOS virtual machine. 
Geometry Wars - The one to which all are compared... Awesome!!!
Everyday Shooter - Really odd and artsy, but darn it's fun.. Even though the analog control of the shooting direction is borked.
(Both available on (but not limited to) steam)
Please. More suggestions needed
