a successor to boneworks mp mod is being developed called "entanglement", it's much smoother than its predecessor, has PVP (not just guns, you can punch and stab), physics sync, finger sync, enemy sync. it's only problem right now is that collisions aren't synced (as in if you walk through a door just by walking through it, the other player won't see the door open)
here's a sneak peak
