When I can get my hands on a stopwatch, I am gonna unlock the Invincibility cheat.
Difficulty Level: Double Agent
Target time: 2:05
its all about where Dr. Doak is standing. hes best when hes standing out side of one of the 3 rooms right around the corner.
i played the SHEET out of this game. got all codes for all my friends in which could never beat me in multi player. (not to boast or anything)
hardest cheat is the caverns in 11 mins and change (forget exact amount) to get double rcp90's if memory serves. been about 12 years. just recalling this off the top of my head.
