Mega Havoc 4
Mega Havoc IV is a bonus area in the Game Boy Advance version of Rayman 3 found in the Pirate Stronghold world.
Level
It has the same environment as that in Boulder Brink and there is only one stage. In this stage, you have to avoid obstacles such as helecopter bombs, and use chain ladders or blue lums to outrun and/or avoid many spikey boulders. The bodyshot power is needed to be used here to break open the wooden bridges over pits. There are 19 Yellow Lums here to collect, though as this is a bonus level, there are no cages to be found.
