The Desolate Hope begins aboard Lun Infinus, an abandoned research station built to simulate human colonization after Earth becomes uninhabitable. Its five sentient computers, known as Derelicts, have spent decades developing increasingly strange simulations while a mysterious virus drains the processing power needed to run them. You play as D-Co 9, a digital helper created from the code of a simple computer game, while the small service robot Coffee relies on you to keep the station and its residents functioning.
The game shifts between distinct forms of play rather than sticking to one combat system. Exploring the station and its simulations uses side-scrolling platforming, with enemies to shoot, powerups and money to collect, and upgrades for your character and virtual battlers. Mini-simulations switch to an overhead, 8-bit dungeon-crawling format where you can earn money and customize battles. When a virus boss appears, combat becomes a mouse-driven, turn-based RPG encounter, putting those upgrades to the test.
That layered structure makes The Desolate Hope a single-player adventure whose action, exploration, and boss fights are interwoven with its story about artificial minds and simulations within simulations. Its shifting genres and offbeat science-fiction premise give the adventure its defining character.
