Evaluation

Procelio is a free-to-play multiplayer vehicle builder/shooter that entered Steam Early Access on June 30, 2026, developed by Ironshell Studios — a small, volunteer-driven team. Since launch, the studio has maintained a consistent stream of updates and communication. Patch 1.6.2 shipped on July 8, 2026 with balance changes, a native Linux branch, and bug fixes. A developer newsletter on July 31, 2026 detailed the ongoing URP rendering engine conversion and plans for ground-focused gameplay improvements. Patch 1.6.3 followed on August 30, 2026 with substantial gameplay, UI, audio, and balance changes, and introduced a new team member. On September 18, 2026, the developer posted a progress update on the URP conversion, confirming active internal playtesting. The most recent update, patch 1.7.0 (URProcelio), shipped on October 3, 2026 — one day before this assessment. This was a large release: it completed the full conversion from HDRP to URP, added a new wheel type (Hauler Wheels), and introduced a new work-in-progress map (Ophir Caldera). Crucially, the patch notes include an explicit forward-looking section titled "The Path Forward," listing work still ahead: expanding ground movement options, improving gamefeel, balancing ground vs. air combat, developing a brand-new core game mode called "Asset Extraction," continuing to refine Ophir Caldera based on community feedback, and adding new parts, modules, and guns. The developer closes by saying "We've still got a lot of work to do in the future." The game is squarely in active Early Access development with a clearly communicated pipeline of upcoming content.

About this game

CALLING ALL PILOTS

Procelio is a modular vehicle builder/shooter inspired by classics of the genre, where every component brings new functions to your robot and any system can break when under fire. Construct combat vehicles ranging from cars, tanks and hovercraft to planes, blimps, and drones- all from the comfort of your orbital home. Load your designs with your choice of ordnance, and fight for dominance in a proxy war over the dunes of Mars. Fight alone or with your coworkers in a multiplayer battle arena fit for chaos.

[RE]DESIGN, REFINE, REPEAT

As a valued employee of Osprey Modular Hardware and Robotics, an arsenal of potential is yours to command. Prove your worth to the company, and you’ll unlock permanent part requisitions to expand your building toolkit. Through a tight loop of building and combat, you’ll learn the best practices of engineering for war. With each deployment, your arsenal expands and your designs can be refined.

While your potential has no limits, your power budget does. Limited AMP space means choices have to be made, and no one machine can truly have it all. Balance your offensive, defensive, support, and mobility capabilities to craft a war machine tailored to your specific play style and needs. 

FIGHT YOUR WAY

There’s more than one way to fight a proxy war. 

  • Brawl your way through the front lines to secure valuable ground and collect the materials necessary for victory. 

  • Go on the defensive, and protect allies and their collected resources directly and indirectly.

  • Embrace the power of logistics, repair and restock allies to keep them in the fight for longer.

  • Take to the skies to provide close-air-support for your allies, or high-altitude aerial bombardment against enemy forces.

  • Sneak your way around to flank and surround enemies, or take out priority targets from afar with long-range firepower.

With an endless combination of weapon systems, movement types, components and modules, you choose your approach to combat amidst a shifting battlefield. If one strategy isn’t working, you can choose another robot from your drop deck and redeploy with a new plan. 

THE FUTURE IS COSTLY

The year is 2152: man has entered a new era. Earth still turns, but the red planet burns. In the first bid of public interplanetary expansion, Hypox Mining Company was granted unrestricted rights to mine, process, and commercially exploit several sectors of Mars. When they arrived to commence operations however, they found the AEGIS colonies which had worked to open Mars to interplanetary traffic in the first place. With the colonies having claimed the same land for their own future plans, confusion and hostilities between the two groups boiled over into violence and sabotage. Enter Osprey Modular Hardware, a monumental research and hardware conglomerate with just the modular warfare package needed to fight a proxy war in a harsh environment, far from the logistics lines of Earth. The ensuing war will be long and hard-fought, but to the victor go the spoils of Mars. 

And to Osprey, of course, the profits.
