Version 1.0.3 brings minor enhancements to the achievements system.

In a world obsessed with massive open worlds and hundred-hour campaigns, “Attack on Inirea” delivers something refreshingly pure; a straight-up arcade shooter that blends frantic action, base defense strategy, and monster-slaying chaos. Developed and published by Seam Entertainme

We are pleased to announce that Attack on Inirea has been tested by us and works well on both Linux and Steam OS. A video of the game being played on the Steam Deck is available below.

We are in the process of testing Attack on Inirea on the Steam Deck. We expect to launch in May 2025 with full support for Windows, Mac, Linux, and Steam Deck.

Attack on Inirea is an arcade-style shooter where you take control of powerful weapons to defend the peaceful village of Inirea from hordes of monsters.
