while it may not work as well as the 3 resistance strategy, i did it by gettinjg it to 2% resistance and then doing the get it to 200 and when it drops to 175 use rocket strategy
i am doing the jungle one and there is two islands connected by a bridge. i killed two out of the three enemies on the bridge, and since i cannot pass over a ememies corpse, i am screwed. is not for all teh bugs and ways of getting stuck i would rate this 5/5, but with all fo them i rate it 3/5
