Get ready for the ultimate showdown in Assault On Proxima, a fast-paced sci-fi FPS that puts you in the ranks of Strike Force Delta to battle the relentless Gacrux alien invaders. The year is 2915, and humanity has begun colonizing star systems close to Sol. On Proxima C5, Terran mining colonies have become the target of a brutal alien assault. As a member of Strike Force Delta—an elite interstellar commando squad—it’s up to you to reclaim the colonies and push back the Gacrux threat. Choose to fight solo, join forces with friends in co-op, or face off in adrenaline-fueled PvP arenas across a stunning, futuristic landscape.


Assault On Proxima offers fluid, intense gunplay designed to get you right into the action. Fight your way through challenging missions that mix skillful shooting with strategic objectives:
Solo Campaign: Brave the alien threat alone, diving into a narrative-driven campaign full of dangerous encounters and larger-than-life alien foes.
4-Player Co-Op: Team up with up to four friends in co-op mode. As enemies grow stronger, teamwork becomes vital to survival and success.
PvP Matches: Compete against other players in fast-paced PvP matches to prove your dominance. Test your skills and tactics in modes like Capture the Flag, Conquest, and Free For All. In multiplayer PvP, choose to fight as the human marines of Strike Force Delta or take on the role of the Gacrux aliens, each side offering unique abilities and playstyles.


Fast-Paced Combat: Assault On Proxima features accessible, adrenaline-filled gunplay that rewards sharp reflexes and skillful play.
Dynamic Scaling in Co-Op: Experience scaling difficulty in co-op mode, where enemies adapt to the strength and coordination of your team.
Over-the-Top Alien Encounters: Every inch of Proxima C5 teems with hostile aliens hell-bent on shooting or eating you first. Face relentless Gacrux invaders with unpredictable tactics, from swarming drones to the massive, armored Gacrux crabs—a towering foe that can be launched into orbit with the right firepower.
Diverse Environments: Navigate a range of treacherous landscapes, from abandoned colonies to alien-infested wilderness, where every mission challenges your survival skill.
Unique Art Style: Immerse yourself in a vibrant comic-book-inspired sci-fi universe that makes every encounter a visual thrill.
Play as One of Four Classes: Choose from Assault, Soldier, Recon, or Medic classes, each tailored to different playstyles. Customize your role with a selection of powerful weapons, character perks, and a range of explosives.


Every bullet fired, every alien vanquished, and every objective completed brings humanity one step closer to reclaiming Proxima C5. Whether you’re shredding alien invaders solo, coordinating tactics in co-op, or testing your mettle in PvP, Assault On Proxima is a high-energy FPS that delivers relentless action and unforgettable moments.

Assault On Proxima for PC starts at €0.59 (€0.99 with fees) at Kinguin, a Steam key, which is 74% under the €3.79 (no fees) it costs on the official store.
That €0.59 (€0.99 with fees) already includes the OCTGOC10 coupon, so apply it at checkout or the store will show you a higher price.
Supply is thin — 4 offers from 4 stores — and thin supply keeps prices steady rather than falling.
That puts it 83% under its average of €3.79 since 2023, so today is a better entry point than most days of its life.
That €3.79 (no fees) key is at its usual price: no bargain, no spike.
Worked out from 899 daily records of the Steam Key for Assault On Proxima across 6 stores. See the full price history.
The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
All 4 offers are Global, so the code redeems on any account no matter where it was created.
