Is there a way i can defeat stiffdeath

Answer from: Kyle Travers
StiffDeath can be beaten by a two-part strategy.

First, you need to take care of the rats that he uses to replenish his health. He'll smash open one of the five boxes if you drop his health low enough, but it's considerably easier if you just smash them yourself. This way, you don't waste time and health trying to weaken Stiff, and, since he's not hurt, he won't replenish his health. After that, it's a variation of the pest-stomping minigame. You need to flip the rats over with Weak, then stomp them with Strong.

Once all the rats are gone, it's time to focus on Stiff. The tables in the middle hold guns. Smash these, or have Stiff do it for you, and pump him full of bullets. Use all the guns, and then go hand-to-hand to take out the rest of his health bar.

His attacks are mostly easy to avoid. Avoid melee attacks with dodge; I think this works with his electricity attack, but don't take it for certain. When he bends over to release a circle of spikes from his back, take cover behind any tables you might have left.

Good luck.
