Jupiter Hell

Players control a marine, technician, or scout on a demon-infested science base on the moons of Jupiter. The labs are procedurally generated and tile-based, shown from a top-down perspective. Combat is turn-based and tactical. Multiple weapons are available, each of which has different strengths, such as stopping power, accuracy, and ammunition capacity.

A queue controls whose turn it is. Shooting, reloading, and other actions push one's next action later in the queue depending on their cost. Fast players or enemies who perform low-cost actions may act multiple times before their opponents. Cover provides protection, but players are encouraged to move around.

ChaosForge previously developed DoomRL, which reimagined the first-person shooter Doom as a traditional ASCII-based roguelike. DoomRL was renamed to DRL after Zenimax, Doom's rights-holder, complained. Jupiter Hell is a spiritual successor to DRL, using a similar premise in an original setting with 3D graphics. Zenimax's cease and desist letter about DoomRL, which was sent during Jupiter Hell's Kickstarter crowdfunding campaign in 2016, ignited widespread coverage on high-profile gaming websites, but ChaosForge said it did not translate into nearly as much interest as the existing community built up around DoomRL. Jupiter Hell entered early access in August 2019 and was released on August 5, 2021.

Jupiter Hell received positive reviews on Metacritic. RPGFan made it an editor's choice and said "while being any good at it requires a time commitment, the rewards are exhilarating". NME called it "a must-have for strategy fans and curious Doom fans alike". Bloody Disgusting said the mash-up of genres "works well" and "provides a compelling game" whether played in short bursts or long-term.
