awww.... but in freeplay / singleplayer , does it lagg?

I haven't done 4 player replays, but I doubt it since you are not establishing a connection with anybody.
It'll certainly run a little slower though

Hopefully they could do it soon...cuz this would be cool...But i do agree that our current computer tecnology cant handle that much, some computers can barely handle shaders and fluid blood by themselves...So when computers get better i think this will be included in toribash multiplayer

i dont mean downgrading. I mean if there would be a better physics to be used in game that doesn't cause too much lag and bugs.

I also wonder why the limbs of your tori pass through each other.

about 4 player in SP. It lag is still there but not like in MP.
Actually, 4 players in MP is doesn't lag much if players are good. Specially when they do not touch too much of their joints.

I think devs or some who doesnt support this thinks of the possible happenings if this would be implemented.
