300 is coming to theaters this spring and (surprise!) it has a video game coming out for it. Collision Studios who made the Camp Lazlo GBA game is handling the game’s development. The trailer below shows the footage of the game after the movie clips and it reminds me of portable God of War with blockier graphics. The slow motion effects during attacks look cool, but it is not clear if that is actual gameplay footage or crafty trailer editing. Also interesting to note is that 300: March to Glory is only scheduled for the PSP and it’s the only game based on the movie. Why would Warner Bros. Interactive Entertainment only choose the PSP? They brought Happy Feet to nearly every console under the sun, except the PSP.
