Monsters vs. Aliens review. Classic Game Room presents a CGRundertow review of Monsters vs. Aliens from Beenox and Activision for the Xbox 360. Based on the DreamWorks movie of the same name, Monsters vs. Aliens is basically every licensed kids game you've ever played. It's an action game so simple, you see all the gameplay it has to offer within the first 30 minutes. You play as a bunch of different characters from the movie, and each one has unique stages of their own. Unfortunately, the levels and gameplay are just a little too mundane for that to make a difference. This video review features video gameplay footage of Monsters vs. Aliens for the Xbox 360 and audio commentary from Classic Game Room's Derek.
