RIG Riot launches on Steam today, September 14, 2026, and its pitch is wonderfully easy to understand: build a ridiculous custom mech, throw it into fast third-person combat, collect weapons and volatile upgrades during roguelike runs, then bring permanent machine parts back to the garage when everything inevitably explodes.
If the obsessive mech-building side of Armored Core appeals to you but you also like the “one more run” structure of action roguelikes, this small solo-developed release is worth having on the radar.
Research basis: Based on the current Steam page, official developer updates, the Steam demo, and the official launch-date trailer. No hands-on play is being claimed.

What is RIG Riot?
RIG Riot is a single-player third-person mech shooter from solo developer Sage Boatman. Instead of handing you one fixed machine, it revolves around building a RIG from a huge pool of permanent parts, then taking that machine through increasingly difficult combat stages.
The moment-to-moment fantasy is heavy metal in the most literal sense. You can build around mobility and long-range sniping, missile barrages and automatic weapons, or heavier setups that get close with shotguns and laser blades.
That is why the Armored Core comparison is useful, even though these are very different games. Both put mech construction, weapon choice, movement style, and build identity at the center of the action. RIG Riot then takes that mechanical obsession in a run-based direction.
Every failed run gives you more robot to mess with
The garage looks like the real rabbit hole.
RIG Riot’s Steam page says there are thousands of permanent parts to discover. Individual parts are assembled from components drawn from different equipment sets, creating a large number of possible combinations rather than a tiny menu of fixed robots.
The developer has also expanded the customization side during development. A July demo update added biped legs, weapon customization, saved weapon loadouts, saved color palettes, and an Arena, alongside new objectives and enemies.
That makes customization more than a cosmetic toy. A lightweight sniper build should behave differently from a chunky close-range machine, while boosters, weapons, internal parts, and other equipment change what your RIG is actually good at.
Then RIG Riot turns the mech game into a roguelike
This is where it stops looking like a straight Armored Core substitute.
During raids, you move through increasingly difficult stages, complete objectives, level up, and hunt for weapons and Volatile Mods that can push the current build in different directions. Finding the right effects and synergies is part of seeing how far that particular run can survive.
Death does not wipe everything. Permanent parts head back into the larger customization loop, so failure can still give you new hardware to experiment with on the next attempt.
That combination is the hook: temporary run-building layered on top of permanent mech-building. One system asks what ridiculous machine you want to own. The other asks what ridiculous version of it you can create before the current run falls apart.
Who should check out RIG Riot?
RIG Riot looks most interesting for players who want buildcraft as much as shooting. If swapping legs, boosters, weapons, internal components, and modifiers sounds more exciting than simply unlocking a stronger gun, this is very much aimed at you.
The roguelike structure is also important. Anyone looking specifically for a handcrafted Armored Core-style campaign should expect a different rhythm here. RIG Riot is built around raids, escalating stages, changing run upgrades, permanent unlocks, and repeated experimentation.
There is already a free Steam demo, and its user reception provides at least an early signal that the idea is connecting with players. At the latest check, the demo held 92% positive reviews from 126 users.

One more run, but make it several tons of machinery
RIG Riot is a small release with a very clean hook. It takes the customization fantasy that makes mech games so easy to obsess over and attaches it to the build experimentation and repeated runs of a roguelike.
It launches on Steam today, September 14. If spending twenty minutes adjusting a robot before spending five minutes turning other robots into scrap sounds completely reasonable to you, this might be today’s Steam release to watch.
