Deal | Free to claim: Action-roguelike game is back on Steam and free to keep for 60 days

After a quiet takedown in early 2024, Bioprototype has returned to Steam, and that too with a detailed apology. The rogue-lite auto-battler, which vanished due to a publishing partner’s violation of Steam rules, is now free to keep for anyone who claims it between May 20 and July 20, 2025.

The sudden delisting, it turns out, wasn’t the developer’s fault. According to a lengthy public note, the game’s publisher BD Games breached platform policy, leading to a permanent account ban. Unfortunately, this took all associated titles down with it, including Bioprototype.

Emprom Game, the studio behind the game, clarified that they weren’t aware of the violations and took responsibility for mismanaging their risk and communication. In the statement, they admitted to poorly handling the aftermath - relying on giveaways via Epic instead of pushing harder for a full reinstatement on Steam.

Now that Bioprototype is back, players who claim the game during the two-month free period will also receive a permanent 20% discount on the full Bio-Series bundle, which includes the recently released sequel Bioweaver. The devs also made it clear that Bioweaver is a separate project, not a renamed version of the original.

Bioprototype itself is a fast-paced, visually chaotic roguelike with neat visual programming mechanics - very reminiscent of Vampire Survivors. Players have to build their own flesh monstrosities using over 80 unique organs, mixing them across 24 characters and skill trees like Bullet Master and Virus Master. The game rewards experimentation and mayhem - throwing players into a constantly mutating arena full of spores, symbiotes, and body horror.

Reception has been mostly positive since the re-launch, though some users are still encountering bugs and missing models. Still, most agree the game’s core is strong, and free is honestly a hard price to beat.
