Update 2021: My glitchless 2h 19m 50s run is now my true any%, but inexplicable rules mean I cannot update this any% officially.

"Info for outdated 3h 31m 47s"

This was an experimental speedrun to test the damage outputs of enemies and see how ammo management and ADAM comes into play. The results are, enemies are weak and easy to avoid, the machine gun is overpowered, ADAM is not worth the time investing (especially if it summons a Big Sister) and Evil Eleanor is cute.
