Zapping Combine soldiers with the supercharged gravity gun was a right lark, a fine moment in Half-Life 2. Today I’ve been larking around with a different type of turbo gravity gun in a new mod, and I think I prefer it. See, it lets me ‘rocketjump.’
HL2 mod Transmissions: Element 120 [official site] is a short singleplayer mod introducing a new zapgun. It blasts balls of concussive force that send enemies and physics objects flying (and its levels are heavy on blastable props) and, of course, you. Look down, jump then blast a ball, and go sailing through the air like a beautiful murderous butterfly.
