Signal Studios has announced that the final DLC expansion for its successful XBLA strategy title, Toy Soldiers, will launch next Wednesday, September 29. The pack, titled "Invasion," will add a new, three-level mini-campaign, 50 Gamerscore worth of new Achievements, some additional enemy units and new driveable vehicles -- most of which are based around the main campaign's alien invasion motif.

You can check out some screenshots of the new, otherworldly content in the gallery posted below and a trailer after the break. If you're jonesing to bust up some more playthings, you'll be able to grab "Invasion" for 400 Microsoft Points ($5).
