Yggdra Union was originally released on the Game Boy Advance and PSP between 2006 and 2008 and was the second in the Dept. Heaven saga of games, following Riviera: The Promised Land. It is a tactical role-playing game that follows the titular character Yggdra's attempts to liberate her homeland, after an invasion. Notably, the game features a complex battle and movement system based on a series of cards, as well as "a Union System", whereby units can team up with nearby allies to launch more deadly attacks.
In 2019, Sting Entertainment remastered the game for Japanese Android and iOS users, with a similarly region-locked port for Nintendo Switch arriving one year later. The remaster included a bunch of handy new features, such as a rewind function, autosave, and speed adjustment controls, and it appears the PC version is also set to add a few more options.
According to the game's Steam page, you'll be able to switch between Japanese and English voice acting at any time, save freely during battle, remap your keyboard controls, and use items infinitely in EASY mode, to name just a few of the additions.
