X-Men: Mutant Wars - Level 5

Here's one from a pro! Cyclops' eye beam is apparently the most powerful attack in the game (Cyclops is also the weakest character I think, perhaps to balance things out) so I use him here. In some levels the beam doesn't kill with one hit though, so he's not as useful in the entire game as he is here. Oh, and there's a way to get a power boost for Wolverine that lasts for the level, ín every level, but I'm not 100% sure on the requirements. Anyway, with the boost he kills every smaller enemy with one hit.
