Spacefleet: Heat Death Prometheus is a realism-focused tactical space RPG set within the Earth-Luna system and its Lagrange points. A hostile fleet is inbound from the Jovian System to reclaim their antimatter drive, and as the new leader of the Prometheus faction you have sixty days to turn a handful of survivors into a defensive fleet capable of stopping them. Every one of those days counts.

The game builds its tactical layer around simplified orbital mechanics, requiring players to flip and burn their way through the space between Earth and Luna. Ship management goes beyond weapons and crew: radiators and heatsinks must be managed to prevent ships from melting, grounding the combat in a physicality that most space games ignore. When engagements do break out, squadrons are commanded in full 3D space combat where positioning carries real consequence.

Building that fleet demands resources, and the paths to earning them vary. Players can trade, hunt bandit fleets for bounties, or gamble at high stakes through a system called Astrocaster. Every credit earned goes toward another railgun slug or laser ship, each purchase narrowing or widening the gap between survival and annihilation when the sixty-day clock runs out.

This standalone demo serves as a free tactical slice of the larger Spacefleet: Heat Death, with player feedback from the Prometheus campaign feeding directly into the development of the full series. The question it poses is simple enough: whether the Prometheus faction becomes a footnote or the beginning of something far more dominant.
