With one to four players, you play through 15 levels based on the movie’s plot, sometimes filled with mildly humorous mayhem. The game suffers from being short, something not uncommon with movie-based games from smaller publishers. Also, in the Wii version, pressing the ‘A’ button twice to jump high doesn’t always work. And the game's difficulty ramps up too quickly.
Although the camera and graphics are nicely tuned, the fact that the double jump doesn’t work well is frustrating. Depending on which alien you choose, you can stun a human, use sharp fingernails to slash, create grenades, or use your teeth. When playing on the Wii, shaking the Wii remote lets you pull off these attacks quickly. Overall, though, Aliens in the Attic has spotty gameplay. Try it before you buy it to make sure it’s for you.
