Well i know that if you beat all the times in "Snake Vs. Monkey" you get the "monkey mask" (dogs will not bark at you), if you beat the best times you get the "Banana Camo" (all food gives you good stamina recovery and tastes great), and if you beat the best "Duel Modes" times on normal you get the "Green Face paint" (grip gauge will not diminish), and if you beat the best times on special you gwt the "DMP Camo" (doubles the naturalt LIFE recovery rate) those are just a few unlockables i know of.
Does anyone know of any more other than the infinity face paint and the stealth "camo"?
As I walk on through this wicked world,
Searching for light in the darkness of insanity,
I ask myself, Is all hope lost?
Is there only pain, and hatred, and misery?
