Overview

Polarity is a fairly simple map, introducing the player to the idea of reversible excursion funnels. Of course, as speedrunners, we like to ignore the normal puzzle elements, so we'll stick with the regular polarity.

Nidboj's alternate ending route

This level can be done in zero (0) portals.

• Hop over to the turret, pick it up, and do 2 turret jumps to get across the gap.
• Kill the frankenturret by dropping it down the gap.
• Pick up the new frankenturret before it hits the ground.
• (as shown) Drop the frankenturret next to the wall and jump on top of it.

The last step is fairly difficult, and there is an easier way found by Nidboj. After grabbing the cube, push it against the right wall while looking up to get it on its side, then slide it down in front of you. Finally, jump onto the side of the cube and drop it, then spam jump.

Full Game Specific

Since we have CFG coming into this level, we can just jump after the entrance door to get as much height as possible without going above the exit door, strafe across the entire level, then use the funnel to get up the rest of the way to the exit door. This will disable our CFG, but we'll get it again later in Laser Catapult.
