Activision released a new demo for Monsters vs. Aliens, this time giving you the chance to try out the PC version of this game based on the upcoming DreamWorks Animation 3D feature film with the same name. The demo features a sample of 3 levels straight from the game. You can choose to play as B.O.B., the indestructible gelatinous mass capable of absorbing and sticking to anything; Missing Link, the macho half-fish, half-ape; or Ginormica, the 49-foot 11-inch tall woman. Each character features a different type of gameplay - B.O.B.'s gameplay centers on platforming and puzzling as he works his way through the inside of a giant robot, while Missing Link focuses on combat with some platforming in his attack from the outside of a giant robot and Ginormica features primarily racing with limited combat as she contributes from the ground in the fight against Gallaxhar and his army of alien robots.
