Publisher Shueisha Games and developer TrueWorld Studios announced a release window for UNYIELDER, their new single-player roguelite looter shooter focused on boss battles.

UNYIELDER is set to launch sometime in May for Windows PC (via Steam), and a playable Prologue demo is now available.

Here’s a rundown on the previously announced game, plus a new trailer:
