Released 2026-08-19. 14 updates since release, the newest 2026-09-17.
Newest update: Atmosphere Shift (2026-09-17)
- The sky above the arena has transformed — new clouds and lighting set a fresh tone for every engagement.
- Pilots now spawn with full armor plating when entering a new zone, ensuring you hit the ground combat-ready.
Earlier update: The Crossing Fix (2026-09-15)
- Mechas no longer teleport between terminals when entering the garage after a survival trip.
- You can now move freely after re-entering the garage, instead of being locked in place for 20 seconds.
Earlier update: Collision Overhaul (2026-09-14)
- Enemy mechas no longer clip through platforms or get stuck on terrain obstacles.
- AI pilots now intelligently navigate around dead ends instead of getting wedged in place.
- Arena now supports up to 4 pilots per room for smoother multiplayer combat.
- Enemy target names now display correctly after spawning on slower connections.
- All five enemy chassis variants maintain their distinct silhouettes in combat.
Earlier update: The War Machine Rises (2026-09-14)
- A colossal rolling sphere replaces the War Machine's wheels — the boss now rides a massive armored orb that crushes terrain as it hunts.
- The boss's core is exposed during enrage: a critical window opens when the War Machine reaches peak fury, and you can strike at its burning heart.
- Four elite barriers now seal the Dead Quarter route — breakthrough each gate to face the boss in its arena, but only if you're strong enough.
- The camera sits lower in combat, closer to your mech's shoulders — sightlines sharpen and the horizon steadies as you aim.
- Visual polish across every place: brighter streets with work lights, clearer fog, and sharper lines make the industrial world read cleaner.
Earlier update: War Machine Overhaul (2026-09-11)
- DEAD QUARTER — WAR MACHINE OVERHAUL
- Explosive high-speed rushes leave wider, livelier fire trails; the boss turns back toward the pilot afterward.
- Faster missiles with larger blast zones and a rapid, clearly telegraphed zigzag laser.
- Larger tank wheels, animated arms, and damage volumes that follow moving parts.
- Four elite-gated route barriers and a sealed boss arena that releases after the encounter.
- Adventure boss damage intake corrected; persistent fire clears on defeat or departure.
- Mission guidance moved to the left, keeping the aiming area clear.
What players say
@vladtheimpaler · 2026-09-17 · played 5 min · 1 heart: “I liked jumping in and seeing how the experience comes together when you have other players around. The concept caught my attention right away, and the overall presentation gives it a distinct identity instead of feeling like another generic multiplayer game. I specially love love the rockets!”

@lego · 2026-09-14 · played 14 min · 1 heart: “I encountered a bug in my 1st survival match. At the start of the match, my mecha got stuck in one position, teleporting up and down, and I couldn't move it. After 20-30 seconds tho, I was able to move again. Weird. Anyway, about the gameplay, this is actually fun and challenging. I reached Wave 7, not sure if I suck or what lol, but I had a great time playing this!”

- @chucky (maker) replied 2026-09-11: “Yeah! I made a big upgrade, now all should feel much smoother! Better UI, better design, combat remastered, etc”
@sunraku · 2026-08-31 · played 2 hrs 4 min · 1 heart: “I love the smoothness of movements in game. The character was not like the other mech battle that feels like heavy to control. The aim was also felt easy and good.”
