Risk of Rain 2 Bosses and the Alloyed Collective DLC

Reviewing
Risk of Rain 2
Hopoo Games
This Risk of Rain 2 bosses guide covers the confirmed boss roster plus a detail worth getting right before anything else: the game's actual 2025 DLC isn't the one most players assume. What Alloyed Collective, the real November 2025 release, actually added gets a clear-eyed look below too.
TL;DR: Confirmed bosses span the main stage rotation (Beetle Queen, Clay Dunestrider, Grandparent, and others) up through Mithrix, the final boss at Commencement. Survivors of the Void and Alloyed Collective each added their own bosses. Alloyed Collective, not Seekers of the Storm, is the actual 2025 DLC: it added 2 survivors, 2 new Teleporter Bosses, 7 stages, and 18 items, and launched to a much cleaner reception than its predecessor's rocky debut.
What are the confirmed bosses in Risk of Rain 2? (quick answer)
The main rotation includes Beetle Queen, Clay Dunestrider, Grandparent, Grovetender, Imp Overlord, Magma Worm, Overloading Worm, Scavenger, Stone Titan, and Wandering Vagrant, confirmed via the game's own wiki. The final boss is Mithrix at Commencement, and beating him loops the run back to Stage 1 rather than ending the game outright.
Key takeaways
- Main-rotation bosses confirmed: Beetle Queen, Clay Dunestrider, Grandparent, Grovetender, Imp Overlord, Magma Worm, Overloading Worm, Scavenger, Stone Titan, Wandering Vagrant
- Mithrix is the final boss at Commencement; beating him loops the run rather than ending it
- Survivors of the Void added Void Devastator, Xi Construct, and the Voidling
- Alloyed Collective (Nov 2025) added Solus Amalgamator and Alloy Hunter as new Teleporter Bosses
- Alloyed Collective's own new final boss was deliberately spoiler-redacted by the developers at launch
- The 2025 DLC is Alloyed Collective, not Seekers of the Storm (which released August 2024)
The core boss rotation
Ten bosses make up the confirmed base-game rotation, each tied to specific stages rather than appearing everywhere: Beetle Queen, Clay Dunestrider, Grandparent, Grovetender, Imp Overlord, Magma Worm, Overloading Worm, Scavenger, Stone Titan, and Wandering Vagrant. Mithrix, "King of Nothing," closes out the main progression at Commencement, the final stage. Beating him doesn't end the game outright: the party loops back to Stage 1 instead, with difficulty scaling further multiplied on top of whatever it had already reached, which is why runs in this game can theoretically continue indefinitely rather than stopping at a fixed final boss the way many roguelites do.
A glacial-themed boss encounter, part of the environmental variety the elite and boss system layers onto standard enemy types.
Elite enemies aren't the same as bosses
Separately from named bosses, any regular monster can spawn as an elite with a powerful modifier attached, confirmed via the wiki's own elite-affix list: Blazing, Overloading, Glacial, Mending, and Gilded at the first tier, with Malachite, Celestine, Twisted, and Collective (the newest, added by Alloyed Collective) at a second, tougher tier. Perfected and Voidtouched exist as special elite variants on top of that. An elite-modified regular enemy can be more dangerous than an actual boss fight depending on the affix and the stage, so don't assume "boss" and "elite" mean the same threat level.
DLC bosses: Survivors of the Void and Alloyed Collective
Survivors of the Void added Void Devastator and Xi Construct as new bosses, plus the Voidling as a special end-of-run encounter tied to that expansion's content.
Alloyed Collective, confirmed directly via its official Nov 18, 2025 patch notes, added Solus Amalgamator and Alloy Hunter as "2 New Teleporter Bosses." Worth noting separately: Solus Control Unit, sometimes assumed to be Alloyed Collective content because of the shared "Solus" naming, actually predates the DLC, coming from an earlier "Skills 2.0" update, even though it does appear in some Alloyed Collective stages. Don't credit it to the new expansion.
Alloyed Collective's own new final boss is a genuinely unusual case: the developers deliberately redacted its name in their own official patch notes as an intentional launch-day spoiler tease. The community-maintained wiki, updated after players found it in-game, names it Solus Heart, encountered in a location called Neural Sanctum. Treat "Solus Heart" as a post-launch community identification rather than something the developers themselves confirmed on day one, since that's genuinely what happened here.

The actual 2025 DLC, and why the confusion happens
Here's the correction worth making explicitly: if you've seen coverage calling Seekers of the Storm "the 2025 DLC," that's wrong. Seekers of the Storm released August 27, 2024, confirmed directly via Steam's own release-date field. The real 2025 expansion is Alloyed Collective, released November 18, 2025 (Switch following in Q1 2026, per official patch notes), confirmed via Steam's appdetails API and official patch notes.
The mix-up is understandable given the games' shared timeline: Seekers of the Storm launched into a genuinely rough reception, roughly 30% positive at the time per contemporaneous outlet coverage, coinciding with much of the original Hopoo Games team departing to join Valve. Gearbox, who took over post-launch support, ran a multi-phase "2.0" recovery effort through the rest of 2024 into 2025, revamping Seeker, False Son, and CHEF's kits along the way (confirmed via the official May 2025 developer diary). That whole recovery arc unfolded gradually enough that "Seekers of the Storm" stayed the more talked-about name in player discussion well past its actual release window, which likely explains why it sometimes gets mistaken for the newer release.
Alloyed Collective, by contrast, launched clean: contemporaneous Steam coverage put it around 96% positive, a sharp turnaround from its predecessor's opening reception. Confirmed contents beyond the bosses and items already covered: 2 new survivors (Operator, Drifter), 6 new enemies, a new elite type (Collective Elite), a new "Solus Family Event," 7 new drone types plus a new "Remote Operation" mechanic letting a dead co-op player pilot an ally drone until revived, 7 new stages plus 1 new loop variant (Iron Auroras), and 5 new interactables.
A boss encounter on one of the game's desert-biome stages, the kind of fight where positioning around hostile adds matters as much as raw damage output.
Is a 4th DLC coming?
Yes, but it hasn't released. "Hallowed Concepts" is confirmed via Steam's own DLC app listing (marked "coming soon," no release date set) and official developer diaries dated as recently as June 2026. Don't treat it as available content: at the time of writing, it's still in development with no confirmed release window.
One of the game's more atmospheric environments, distinct from the brighter surface stages most of the base rotation takes place in.
