Just take a boomerang, throw it, and spin it 10s avoiding it when it comes back. We must first destroy the walls to have space.
Here is a method to unlock this achievement with a second controller. Start a game with these settings:
- Difficulty Bots: Disabled
- Game mode: Capture the flag
- Time: 5:00
- Level: First Flag
Note: In this video, I made the boomerang spin much more than necessary.
