game is available to play online @ http://instantaction.com
it is like QL launched from browser

it has 2 maps for now (+1 map coming soon) playable in DM, TDM, CTF. it is really fast and a lot of fun. takes quite some skill to fly/slide around efficiently.

atm it's more projectile weapons oriented.

you need godlike aim to hit a moving target with the sniper rifle in this game, plus you need to charge the rifle ~2 seconds and can't activate jets when you hold the charge. well at least it's 1 shot/1 kill.

also the chaingun has some spread and it's not quite instant.

no xerp either :D

PS: InstantAction has some other nice games like Rokkitball (basketball with rocket launchers). check them out :)
