ok, in momentum missile 2, go to construct mode. put invincibility on and make enemies come from both side. put yourself in the middle. you may do any combo of enemies you want, but make sure the respawn time is 10. enemy count is 12. heres the important part: make sure crazy acceleration is on. respawn pattern 2. you can do everything else how you like it. after about 5 min it seems like there is no enemies, but they are really just going crazy fast. most collisions occur with an instant kill for both of the robots, and they also occur near the energy pad (thats why i said put invincibillity on). I Hope you like the trick just as much as i do!
