Aaargh! is an action game developed by Arcadia System and released in 1988. It was inspired by the arcade game Rampage, which was quite popular during that time.
In Aaargh!, we control a giant monster, either an Ogre or a Lizard, with the goal of crushing and destroying everything in its path, across different lands and periods of history.
Our goal is to find five Roc's eggs hidden among the destroyed scenery. Once an egg was uncovered, the two monsters would fight for possession of the egg in a one-on-one battle.
When five eggs were found, the monsters made their way to the volcano, working their way around the lava flows to reach the top and claim the Golden Egg for the ultimate victory.
