Fast paced game

Team Fortress 2

You could try hawken, and Battlefield 3

You can subscribe to the closed beta of Dirty Bomb (from the makers of Enemy Territory).

Hotline Miami

Try Gotham City Imposters

Magicka: Wizard Wars? Though it is not an FPS, so probably not what you want.

reborn.gg
BibleThump

minion rush lol

Tribes: Ascend. Most interesting CTF I've ever played.

Xonotic is pretty good. Haven't played it in a while so I don't know how the servers are

Magicka : Wizard Wars

Fistful of Frags, Loadout

Warframe?

rush bros... no really, its fast

:P

Quake Live

One Finger Death Punch.

Non-competitive Counter Strike GO

Flappy Bird

Call of duty: Black Ops 2. This is a really fast paced game, the game mostly has small maps, so if you land into a full server. It's going to be chaos.

For that person who said Battlefield 3, it's not. I like it better than Call of Duty in graphics, gameplay, and map wise. But I feel that the game is just to slow.

Any touhou game try lunatic mode.
