The Halo 3 Legendary Map Pack that we’ve been talking about over the past couple weeks hit Xbox Live today. Great, but if you plan on purchasing Tecmo’s upcoming Xbox 360 title Ninja Gaiden II, you may want to hold off on splurging on that map pack.

Why? Retailer Circuit City is offering a free voucher code for the map pack to anyone who pre-orders Ninja Gaiden II from their website. The only real drawback here is that it’ll take a week for Circuit City to send the code over to your email. But hell, it’s free!
