Anyone know where I can find and download these weapons, even if they just come up with the map itself?
I would like amy sorts of awesome custom weapon mods for Sven Co-op that aren't just boring primitive hitscan fire arms clone. Any actual flamethrower and tesla like weapons would be appreciated.
