Professor Evil and The Citadel of Time is a cooperative game: Team up with your fellow adventurers to sneak into the mansion and recover the treasures before it's too late! You'll have to work together if you want to beat him! Can you grab the treasures before time runs out, or will these priceless artefacts be lost forever? The race is on!
