Can you grab the Mona Lisa, the Rosetta Stone and Excalibur before time runs out, or will these priceless artifacts be lost forever? The race is on! Professor Evil and the Citadel of Time is a cooperative game in which the professor built a time machine to steal some of history’s most famous treasures and it’s your job to rescue them! He’s locked them away in his castle and devised a series of traps to keep them safe. Team up with your fellow adventurers to sneak into the castle and recover the treasures. Plan carefully and use your unique skills to unlock doors, deactivate the traps, distract the professor and stay out of his way. You’ll have to work together if you want to beat the professor.
