Come November 30th, you'll have a few more maps available to get your Killionaire on. The kind folks at Bungie.net have constructed three slick new settings for us would-be Spartans to craft our kills. What this means is just new locales to play SWAT and Infection, over, and over, and over.
The maps - Tempest, Breakpoint, and Anchor 9 - should tickle the fancy of most Halo: Reach players, as it appears there is a good balance of open-space, thinking men's battles and cramped, clusterfuck action between them. Never hesitant to pile on the achievements, there will also be an extra 250 Gamerscore for the seasoned achievement whore to earn.
The $10 price tag seems reasonable, though maybe that's in part to expecting any little piece of DLC to cost at least 1200 points.
