Abyssal Colossus is the boss that Micky faces at the end of the Ghost Ship mission and the largest enemy in the mod. This gargantuan abyssal monstrosity is so massive you cannot use conventional weapons to kill it. Thankfully, it's also not really paying attention to you, being too busy smashing the ship. It does, however, spawn scores of other demons. To defeat it, you need to transport huge rail cannon from the lower loading docks to the front deck and activate it several times to kill the monster before it destroys the ship.

Trivia[]
- Fight with the Abyssal Colossus is probably somewhat inspired by the fight with Icon of Sin from Doom II.
- Its sprite resemble Gromaides from Contra 4.
