Isotx has announced a free expansion pack for its new RTS/FPS hybrid, Iron Grip: Warlord, available to all current and future players called the Winter Offensive.

Starting December 22nd, Offensive will be available for digital download through their webstore (http://webstore.isotx.com). In order to access this free new content, players must own the original game first and then undergo a simple and quick patching process to upgrade.

Iron Grip: Warlord Winter Offensive will include three new units, one new level, a new soundtrack, and a myriad of technical changes and bug fixes. Isotx hopes to reliably update and add new, free content to the game every few months - stating that "while this expansion is the first, it is certainly not the last. We have hopes to continue to add value to our title and thank our growing community for playing our first commercial release."
