No, we didn't vomit on the picture above. That's a Halo 3 heatmap, an upcoming feature of Bungie.net. This technology (which Bungie has actually been using for a while to help balance their levels) allows players to look at a number of statistics for each map, including the locations of kills, and the weapons used most often. It's just one neat addition the Bungie crew announced in their weekly update.
Considering Halo 3's ridonkulously successful launch, the guys and gals at Bungie should be sitting on some private beach right now, drinking out of diamond encrusted goblets, smoking tightly-rolled cigars made of money. Instead, they're hard at work, fixing various in-game bugs and updating the Matchmaking playlists (Rocket Race FTW). We've got a complete list of those updates after the jump.
No downloadable content was officially dated, but hopefully, we won't be waiting too much longer. According to Bungie, "things are in motion and the DLC bullet train is making a bee line straight for your face."
