Oddworld: Soulstorm

Simply complete five levels rescuing fewer than 80% of Mudokons in that level. The pause menu will tell you your progress on each level and you can click on Level Select from the main menu and count how many levels you have negative Quarma in (they'll be indicated by a red Mudokon face). You'll get this as you work on your Bad Playthrough (Step 1 of the Roadmap).
