Might've been me who posted the one about revolver -> minigun. But that one is only for the challenge, I can't seem to find a much harder tactic (Except for like, original to minigun, but that's just ridiculus), or doing lvl 5 with some really shitty weapons. Me and the NP proved that it actually is doable to go dual Revolver to Miniguns a few days ago. Or atleast we almost did, we died at the point where I, player 1, had the MG, and NP had 12395 $. In other words, we were just about 1 penguin away from the ultimate victory. The Mac 10 to MG seems like some fun shit, but a little bit too easy maybe. But if you wanna play around and just finish the game, I guess it's a really fun tactic ^^.
