[Knight of Gondor]

I've defeated Gollum on single mode. It's hard. Really, you have to wait until the game decides to make him lose his balance. When he gets near the edge and then waves his arms, off-balance, THAT'S the only time you can use physical attack to knock him off.

The problem is, he simply WILL NOT lose his balance in co-op mode! We've tried over and over, because it would be fun to play the two Palantir levels combo, but we can't get through Gollum! Not to mention using cheat codes in combo games. Gollum refuses to fall off. Is this just a game glitch on my part?
