When I look at this video it seems pretty fast faced:

I play with friends sometimes, it's fast but a bit different from qw. The scene is even smaller than qw's.
But it's pretty fun.

Try it out, its free

Fun fact. The mod they are playing (pk++), primevil is working on that and has made the bright items and hud you see

it's too easy to speedup in pk - just jump forward as far as i remember. not as hardcore as qw))

Actually I'm so used to speedjumping in QW that is seems more difficult in Painkiller

rocketjumping through teleporters looks fun

Well, if the scene is even smaller, I won't bother. Still makes me wonder sometimes why some games last and others don't... I know ppl have different ideas about that.

cool grafics. the rest seems pretty cool as well.

edit: when did they start making shitty fps only i wonder?

I think Painkiller failed because of the shitty netcode it had on release. I can remember trying to play some ffa with more then 4 players and it was unplayable. Duel was fine, but duel alone is not enough to gain a big playerbase.
