Run for your lives! Aliens with ray guns and giant robots have come to take over the Earth, and our only hope of salvation is ... Monsters. Frightening as that may be, the video game based on the soon-to-be-released 3D CGI animation is actually not so scary and quite fun for a movie-tie-in game. Monsters vs Aliens is available on multiple platforms that include the PC, Xbox 360, PlayStation 2, PlayStation 3 Nintendo Wii and DS. The PlayStation Portable has been left out for some reason. The game is a fun title that both children and adults will enjoy. Its main story mode can be played alone or using the 'Jump-in Jump-Out' co-op mode with a friend. Gamers take on the role of three of the monsters from the movie. They alternate between the martial arts prowess of the Missing Link, a half-fish half-ape creature, the gooey B.O.B., monsters that stick to walls, swallow and spit out bad guys, and last but not least, the very leggy Ginormica, a 15 metres tall woman. Each level is tailored to each character's unique abilities and makes the game a combo of three different types of game play. Ginormica's levels are similar to skate/snowboarding games, while The Missing Link's are 3D action platforming, and B.O.B.'s is a combo of stealth and 3D platforming. Player two controls a cursor, and acting as Dr Cockroach can slow down enemies and grab certain items. Littered throughout the levels are DNA samples that act as the game's currency which can be used in Dr Cockroach's lab to unlock movie stills, character art and concept sketches. Fans of the movie will enjoy this. In the lab there are also several mini-games that have to be completed before you can unlock more things. Graphically, the game parallels the movie quite well although the Wii and PS2 versions graphics are a little less refined. Overall this is a solid game that gamers and fans can have a lot of fun with.
