Telefragging isn't from Halo. It's from a bunch of different FPS games.
And the translocater is just cool. Quit jumping on the "OMG ITS FROM NOTER GAM" bandwagon. Some of the best mods on this game have been remakes of other weapons.
portal gun, gravity gun, etc.
I've never played UT but that translocater sounds cool, and i never knew that Telefragging was in halo O_o
but now that i think about it... all you really need todo is when a player spawns you make a projectile explodeison, (how2spell?) only catch is.. is that you need to make it so the spawning player doesn't get hurt/killed
