Sigma from Megaman X is just a total loser
i eventually beat the hell outta him after i saw the pattern of the man, the dog, and the kick ass robo machine thingy
damn those eletrical shocks basically killed you in one shot
also, touch the claws and you are pretty much dead
the Dog is simple, you jump around on the sides, charging up your blaster, then when you get to red, you jump down, wait for doggy, then let loose
Sigma regular form was also ez, wielding only a bludgeoning weapon: a lightsaber??, he can only jump at you trying to kill you with just a swing
i find that if you maintain your position near the upper right or left corner of the wall, you can wait for him to scale the walls, and then jump back down, then you let loose when your waiting
ive eventually beaten the robo mech sigma after i used up all 4 of my sub tanks, most of my weapons, and left around 5 bars of health
if anyone has beaten this guy, plz discuss strat
