Mission 26

This level starts on a platform with the dangerous pink crap around. It is safest to stay near the very middle of the platform.

Jump off it when you get to the top and then race to the right as a bunch of the pink blocks will spawn to your left. You need to dash and use the hover pack for speed. You might need to dodge one or two of the fast ones before you can jump down to "safety."

The area below has two portals looping slow moving large bullets and another set of portals on the floor looping death balls. Hover to the left side of the room, destroy the barrier above you, and make your way into the Gate room.

If you end up fighting the Overlord, then luring him into the area with the death balls is a good way to kill him - you just need to activate Blue mode.
