Take the Bullet control configuration, if anyone is wondering.
Stick: View. Inverted by default. Patched by MegaVolt.
X/Y/A/B: Movement.
R: Shoot.
L: Zoom using regular weapons.
L+Y: Zoom using sniper rifle.
L+A: Crouch.
L+X/B: Lean left/right.
L+Down: NPC commands (wait, follow and interact).
L+Up: NPC commands. These ones do not work in this prototype, afaik.
START: Does not work ingame.
I'd say (warning, wild speculation here) Take the Bullet was the very first version of the Raven Software's Soldier of Fortune Dreamcast (the disc based game with the longest loading screens of all time) engine. It has exactly the same control scheme, sniper rifle works exactly the same, gameplay feels the same and Take the Bullet even has a gore system.
