Find yourself aboard a giant spaceship in IHAS, a gripping Sci-Fi adventure handcrafted by a solo Ukrainian developer. Experience intense FPS action, mind-bending puzzles, and epic boss battles.
Handcrafted by a Ukrainian solo developer:

Wake up aboard a giant spaceship in this Sci-Fi Action-Puzzle FPS. With no recollection of your past, you are guided by a familiar voice claiming to be your friend.
Swarming with hostile robots, you must make your way through the vessel, looking for an escape. As you navigate through energy gateways and shifting corridors, a lingering sense of foreboding tells you that secrets lie not far beneath the surface.

Your mission unfolds: As you venture through the ship, conquer the challenges that you face, and unearth your route to freedom, you find that you need to harness the potential of cybernetic enhancement. Seek out upgrade chips and learn to utilise them.

As you rove deeper, you realise that your enemies grow stronger. Equip your weapon with different mods to unlock its full potential. From a powerful laser beam to a hefty shotgun, customise your weapon to match your combat style.
