Cristiano Ronaldo Underworld Football is a football game with an unusual premise. The sport is being threatened as The Underworld and it's demons, spirits and other ghostly creatures is attempting to take the game away from the humans. Now it's time for Cristiano Ronaldo to bring back the game. He has been chosen as the leader of a team of humans who has to enter the Underworld Tournament and defeat four teams of supernatural beings: skeletons, green skinned creatures, ice trolls and succubae demons.
The game consists of single quick matches and a cup. The cup involves playing each underworld team in order and as matches are won the teams are unlocked in the quick match mode. The matches are viewed from an elevated scrolling side perspective and there are five players on each side. The main difference from other football games is that super powers can be used. Each opponent has its own super power and the player acquires them by winning the matches. During matches the powers can be used once the player's power bar is fully charged.
