Time to break out the obscure weapons, can't decide which one I would have in a game
Darkwatch- I swear to god some of the best bloody weapons ever! Quad barrel shotguns with the equivalents of axe heads grafted onto the handles were friggin sweet.
Garry's Mod- Thousands of sweet SWEPS keep the game interesting. The real catch from the game would have to be the Rocket Propelled Chainsaws and the One Two Punch SWEP
Turok (Original N64)- What the hell happened to time traveling Indian!? Anyway, the best weapon from this game would have to be the staff, no idea what it was called but it acted like a death ray combined with a force explosion, pure awesome with Inf Ammo turned on.
Turok 2 onwards- The Shredder, shotgun that fires bouncing ray pellets
Timesplitters 2- Grenade launcher, flaming and frag grenades, good times.
