<< Hrm, not sure why I never thought of rocket jumping >>
Because it's a major pain in the ass. Even though I used that strategy, you take a lot of damage when you do it. It's not like rocket jumping in quake. You don't get much lift on your jumps, there isn't much control in the air in SS, so you either have to time it perfect, or fire two rockets in a row to do it. I had full shields and energy, and it took me down to like 30 energy. It worked though. I tried running backwards and firing the grenades, but they would end up ganging up on me too quickm, and before I knew it, I was hurting myself with the blasts too.
