Haven’t downloaded the Halo 3: Legendary Map Pack yet? You might want to reconsider doing so. Circuit City is holding a special pre-order campaign for Ninja Gaiden II, giving away a free download of the Halo 3 map pack when you pre-order the game. The only downside is you’ll have to wait about a week to get the download code via e-mail from Circuit City. If you’re looking to save some money, though, it’ll save you $10.
