6. WAGH reloads all your ammunitions, the only time you should be reloading is while waiting for doors or elevators or the rocket launcher when all your other ammo is depleted.

7. If you're too nervous to switch weapons in a run, use Six-Shoota, Snazzgun, Boomstikk, Gitseeka Missile and Skorcha. (Six-Shoota and Boomstikk deal high damage, if you quickly switch betwen them the most and the Gitseeka is great in general)

8 ) Use the Snazzgun for mainly gun jumping, because its normal damage output is weak (Gun jumping is when you fire the Snazzgun backwards while repeatedly jumping for insane mobility)

9 ) Use the Snazzgun WAGH for single targets and tight crowds and the Gitseeka WAGH for every other instance.

10 ) If you plan to switch weapons during your run, switch before the Baneblade to Buzzsaw (and back to Skorcha afterwards) and before you press the red button on the Ork ship to Rokkit Launcher.

These are my additions AZRAEL179 was missing in my opinion.
