XBLM sale on Halo: Reach, Sonic 4, and more

Sonic 4 and Ghostbusters: Sanctum of Slime

Microsoft has once again outlined the next two weeks of Xbox Live Marketplace Arcade games, discounts, Games on Demand, and other assorted goodies.

Halo: Reach delivered digitally through Games on Demand will be $49.99 for one week only, starting today, no doubt to promote the launch of the Defiant Map Pack. And if you love Batman but don't yet own Arkham Asylum, you don't exist -- but the game is getting a price drop to $29.99 starting today anyway.

After Full House Poker hits Xbox Live Arcade next week, we can anticipate Ghostbusters: Sanctum of Slime and Swarm on March 23, followed by Seisou Kouki Strania, Islands of Wakfu, and Rush'N Attack Ex-Patriot on March 30. Each game is $10 except for Swarm, which will go for $15.

If you're more in the mood for Arcade discounts, Sonic the Hedgehog 4: Episode 1 will go down to $10 the week of March 22. Then, the week of March 29, A World of Keflings, Raskulls, Worms 2: Armageddon, and the Armageddon DLC "Battle Pack" will all be 50% off. Keep in mind these discounts are for Gold members only.

In what has to be one of the stranger pairings we've seen, Call of Juarez, and Cloudy with a Chance of Meatballs will come to Games on Demand on March 22. Then H.A.W.X. 2 and Split/Second will hit on March 29.

Finally, you can dress up your Avatars with aviator duds, baseball gear, and zombie pets on March 17, 24, and 31, respectively.
