Beyond The Portal — ポータルの彼方へ
The Odd Shooter
Beyond The Portal is a first-person 3D action shooter where you follow a mysterious notebook's instructions — and end up somewhere far stranger than you bargained for.

Starting in a strange room with nothing but your hands, you'll discover a growing arsenal of bizarre weapons, step through a glowing purple portal, and fight your way across two increasingly dangerous dimensions: the industrial chaos of GDev HQ and the crumbling heat of the Lava Zone.
