First go to the planet Mylon and then get out your flux rifle. Then go to the very end of the platform at the very beginning of the level. Next shot both of the robonoid commender's. It will take some time to beat them but each shot upgrades your rifle to the v3. Then it takes 2 shots. If they both die (they will)just jump off and start over. Just keep doing this till it is upgraded all the way.

When you have the double bladed sword go to the Starship Phoenix, then go to the bridge with your sword out his sword gets out of his hand so it looks like he is using the force.

When you do the aniliation nation challenge where you are fight the scorpion thingie robot(you need the N60 storm) when it switches to the N60 storm you hold the button to straif and fire when it runs out it will switch but it keeps fiering the last guns bullets.
