What's the heart power up at 0:38?

@Tattoo247 It's a Margwa heart. It kills all enemies on the map apart from dogs and bosses, and as well as being in the regular drop cycle, one will drop every time you remove/shoot the head off a Margwa. 

What the video doesn't show is how to access the robot. The best thing to do is boost up for the raps at the start of the round, then when it runs out boost up again for any nukes you missed. At the peak of the hill spin 180 degrees and boost again in the direction of the robot and you will float over to it. (sometimes the raps does not spawn solo so all items can be collected in 2 boosts instead of 3)
