It looks like our friends over at Microsoft have outed a quartet of new Xbox Live games that will be delivered to the Windows Phone Marketplace in the not-too-distant future. Being billed as “optimized for the newest Windows Phone 7.5,” the aforementioned — and somewhat familiar — titles include: Age of Zombies by Halfbrick, Bullet Asylum by UberGeekGames, geoDefense Swarm by Critical Thought, and Tamagotchi by Namco.

Now, why are these touchscreen-tickling titles familiar? Three of the four have been proving their mettle on other mobile platforms. GeoDefense Swarm and Tamagotchi are currently available in the iOS App Store; Age of Zombies is available in both the Android Market and iOS App Store; and Bullet Asylum has been in the works for some time — we were treated to a video preview last summer, which you’ll find below.
