Severance - blade of Darkness should run fine.. i tried it not long ago with the 1 patch thats out for it.. still ran fine controlls wern't too bad.
Enclave was a great game, fairly mindless but good fun, pc port was fantastic.
Whats wrong with halo? apart from the fact that 5+ years ago it was meant to run flawlessly on a gf2gts?
and now it crawls on dx9 cards nah not much wrong there.. oh wait yeah gearbox cant port for shit
