Mutants everywhere rejoice! Apparently, one of Professor X's mutant powers is to go on sale on the day when no one believes anything they read on the internet. Today only, X-Men Arcade, the Xbox Live Arcade version, specifically, is on sale for 75% off. That's 200 MS points, or two fiddy in US dollars. You'll recall we were quite impressed with the update of the early 90s classic. Any fan of co-op should go get a copy immediately, at this price. But hurry, the deal will BAMF away, just like Nightcrawler, very soon.
