Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“I want to build Spacefleet: Heat Death with the community. Early Access gives players the opportunity to help shape the game while it's still flexible, especially when it comes to balance, features, and overall gameplay loop. The foundation is already strong, but our players' feedback will be essential in guiding its direction and ensuring it lives up to its full potential.”

Approximately how long will this game be in Early Access?

“I expect this game to be in Early Access for six to twelve months.”

How is the full version planned to differ from the Early Access version?

“During Early Access, I plan to focus on the core gameplay loop and then add more features. For the final version, I aim to have all phases implemented and more polished content, guided by community feedback. Our current development roadmap includes the following phases:
- Basic combat (completed)
- Strategic map (completed)
- Power and heat systems
- Stations and trade (completed)
- Tactical combat (completed)
- Tutorial
- Factions and AI”

What is the current state of the Early Access version?

“Currently, the game features the following:
- Orbital navigation around the Earth-Luna system (Flip and burns, orbits, intercepts)
- Stations, resources, trade, and the economy system
- 3D Tactical Map movement
- Tactical combat (PDCs, railguns, missiles, lasers, heat and power management)”

Will the game be priced differently during and after Early Access?

“Yes, the current price is lowered in order to reflect its early state, which should also act as a discount for those who would like to support the project this early. The finished game's price may be higher based on community feedback.”

How are you planning on involving the Community in your development process?

“I'll be sharing regular devlogs, patch notes, and community polls through YouTube and Steam updates. I read as many comments and messages as I can, and many of the game's current features were directly shaped by community feedback (like the exhaust plumes!). Players will be able to suggest ideas, report bugs, and help prioritize new features. I'll be listening every step of the way.”

About This Game

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.

OVERVIEW

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.

PROOF-OF-CONCEPT

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!
