Take out those tax frustrations on your fellow space marines today: Bungie has released three new Halo 3 multiplayer maps for purchase on Xbox LIVE. This Legendary Map pack also includes new Forge options and ways to share custom Halo 3 content. Plus there’s a special offer: for a limited time, people who buy the maps get four months of Bungie Pro for free. For those of you who don’t know, that means you get 24 storage slots and a maximum of 250 MB for your saved content. Yeehaw.

Maybe this free offer is an attempt to get some players back who’ve more recently made Call of Duty 4 the most played game in Xbox LIVE.
