You can also upgrade (purchase) additional moves as well as develop and equip technology. But these upgrades do significantly improve your performance/ability in the game. I finished the game on Scout level which I found challenging (cos I is gaming noobz), but I'm currently playing on the next level up and I'm actually finding it easier because of the more upgraded weapons, tech & skill sets that I'm packing which I didn't have the first time round.

The jumping levels are still annoying as hell. If only there were a jetpack (surely Sideswipe should have it!).
