Unreal Engine and iPhone showpiece Infinity Blade is set to get another free update on Thursday, adding multiplayer support among other new additions. The "Arena" content pack will let you take on the role of a Titan or Knight and challenge your friends to 1v1 matches through the Game Center app.
In addition, the content update will include a Survivor mode, new holiday-themed helms, and more than two dozen new items including magic rings, swords, shields, and helmets. You'll also get Facebook integration and new Achievements to show off your progress.
This is another free content update for Infinity Blade, after developer Chair Entertainment added new items and raised the level cap in December. These free updates may be helping them give app sales a bump without dropping their comparatively expensive ($5.99) iPhone game down to the more standard 99 cent level.
