In the 23rd century, Earth orbit is flooded with debris from constant warfare. Countries, megacorporations, and mercenaries are fighting for control. Take contracts, build your warfleets, and dominate the Earth-Luna system in this realism-focused strategy RPG!

The Expanse meets Mount and Blade in Spacefleet: Heat Death, a realism-focused tactical space RPG that combines fleet management, orbital maneuvers, and full 3D space combat in the Earth-Luna system and its Lagrange points.
Your old life was never perfect. But in orbit, you can make a name for yourself. Trader, bounty hunter, or fleet commander: become who you want to be in this hard sci-fi world. From scraping by on trade contracts and gambling wins, you will slowly but surely work your way towards building an empire that will reach the stars.


Use three-dimensional space to your advantage! Utilize lasers, railguns, and missiles to destroy the enemy as you manage your ships' heat levels and command damage control teams.


Flip-and-burn your way through the Earth-Luna system. Command fleets, dock with stations, and plan orbital intercepts. Gamble, trade resources, and hunt for bounties. HEAT DEATH's economy is based on supply and demand.


Every ship is composed of multiple modules with important functions. Lose your drive, and the ship becomes a sitting duck. Lose your crew module, and the ship won't receive orders. Lose your radiators, and the ship burns from the inside.
Group your ships into different squadrons and execute your plan of attack!


In this game, "HEAT DEATH" takes on a whole new meaning. Careful heat management and efficient use of power-hungry systems are vital to keeping your ship from melting and its crew from baking alive.
Spacefleet: Heat Death is a proof-of-concept “lite” version of a much larger game, Spacefleet: Sol, which will span the entire solar system and have more core features.
By buying Heat Death, you're supporting the development of Sol and helping shape its foundation.
A free demo for Heat Death is also available. Once Sol releases, Heat Death will become free-to-play!
