I thought it might be a good idea for those with the BBE to help those attempting it in a thread like this. Once enough information has been accumulated it could be cleaned up and put on the Wiki. I'll start with some basics.
- Skip all Cutscenes, they add to your total time.
- Tranquilizing a Frog while on a wall will cause her to fall and die, but will not count towards your kills.
- Ammo cannot be purchased for non-lethal weapons in The Boss Extreme, so stock up on Emotion and Anesthetic rounds in your previous run.
- The Solar Gun is invaluable during the Eastern Europe Chase sequence and your fight with Vamp.
- Raging Raven can be 1hit K.O'd in her Beast form with a fully charged Rail Gun hit to the head. A body shot will do 75% of her health.
