After two years in Early Access, Them's Fightin' Herds entered full release with a fancy 1.0 launch trailer as seen above. More than just a side-on fighter, it contains a story mode (releasing episodically), an online lobby in the style of a JRPG overworld, a multiplayer dungeon crawl mode called the "salt mines", and some pretty complete-looking tutorial and training modes.
Them's Fightin' Herds is available on the Humble Store and Steam.
