Enjoy it while it lasts, Halo 3, because while you may be at the top of the Xbox LIVE Activity Chart this week… and maybe next week and possibly the week after, it can’t possibly last after the release of Call of Duty: Modern Warfare 2 over the week of November 17th. Soak it up.

In fact, the assault on Halo 3’s dominance may start a little early, after Xbox LIVE’s Deal of the Week this week reduced the price of Call of Duty 4’s Variety Map Pack by half, which gives just that little bit more of an incentive for CoD 4 (currently at No. 2 on the activity chart) players to get online and shoot some fools in the face in a variety of different ways. cough

Top selling Xbox LIVE Arcade titles for this week include Trials HD (once again) at No. 1, SOUTH PARK LET’S GO TOWER DEFENSE PLAY! at No. 2 and Zombie Apocalypse at No. 3.

The Xbox LIVE Indie Games sales list is mixed up a tiny bit as Avatar Drop reaches No. 1 and I MAED A GAM3 W1TH Z0MB1ES!!!1 shifts down to No. 2, with the ever-present Headshot sitting stubbornly at No. 3.
