A few months ago I thought of a pacifist speedrun where you had to beat the game without killing anyone (but you could still attack them so you can beat civ stage). I have a few more ideas for speedruns a moderator could add. I will add more speedruns when I come up with them.

Grox%: You have to ally with the Grox to finish this speedrun. Timing starts when you start Cell Stage. Timing ends when you confirm allying with the Grox.

Earth%: You have to make it to the Sol system and find Earth. Timing starts when you start Cell Stage. Timing ends when you find Earth and receive the "Manifest Destiny" achievement.
