Evaluation

Astrox Imperium is a solo-developed space sandbox game that has been in Early Access since March 22, 2019. On February 6, 2025, the developer posted a candid personal update explaining he had been through difficult life events and laid out a clear end-game plan: polish the game into a complete sandbox experience, convert the campaign into a tutorial, and release v1.0 before stepping away from Steam game development. Rather than going quiet, the developer has continued delivering on that plan at a strong pace. The previous evaluation noted weekly updates through May 4, 2025 (Build 157), and as of today — September 23, 2026 — a new update has just arrived: Build 158, posted today, upgrades the engine to Unity 6 (version 6000.3.3f1) and includes substantial changes to the cloaking system, AI behavior for mining/salvaging NPCs, and various bug fixes and UI adjustments. The May 4, 2025 post (Build 157) stated explicitly: "I know I said I would be doing 12 updates before releasing v1.0. It's close, but not there yet. I will continue with the updates until I nail down some loose mechanics, and redo the tutorial." That v1.0 milestone has not been announced as reached. The developer has not posted a completion or final-update statement at any point. The September 23, 2026 update demonstrates the developer is still actively working on the game and has not stepped away. The game remains in Early Access with a v1.0 release still in progress.

About this game


Astrox Imperium is my attempt to create the space game that I wanted to play, but no one had created. I wanted a single player, open-world space game that is similar to games I enjoyed, like Homeworld and EVE, with economies, factions, and a simple story. A game where I could set all the parameters, and the universe would come alive with new challenges each time I played. I tried to take the best of what I liked from many of my favorite space games, and combine them into something simple but deep, familiar yet fresh, and enjoyably addicting to play.


The main game play loops are fairly simple, and familiar. What makes Astrox Imperium unique, is the way that you can easily glide between the various loops to maintain a nice level of progression, without it feeling to slow or too fast. You have complete control over how the universe is generated. You can make it long and 'grindy', or tweak the endless sandbox settings for fast and rapid progression to access all the mechanics the game has to offer.


As with most space games of this genre, mining is a big mechanic of Astrox. It is the easiest way to earn credits. You can also complete contract missions. These are randomly generated missions that offer a variety of task and objectives to complete. Some of these contracts are combat missions that will involve raiders, pirates, and sometimes regular npcs. The combat missions offer a bit more action to an otherwise relaxed game. The rate at which you choose to progress is up to you. There are a number of small, interesting little mechanics sprinkled throughout the game that were given a lot of thought and care, but you will not find anything groundbreaking or innovative here. This game is meant to feel comfortable and familiar. The game play loops are designed to be simple enough to understand quickly, and complex enough to enjoy over many hours of play.


Many of the classic mechanics from the space game genre have been incorporated into Astrox Imperium. Basic interface controls were designed using elements from some RTS and FPS games. All the fan favorites and core game play elements have been included; mining, crafting, trading, refining, fleets, combat, exploration, survival, and more. This game will seem familiar to fans of the space survival / exploration game genre. Here is a list of features that are currently in the game.

What NOT to expect

  • Astrox is NOT a fast-paced space shooter... there is no mouse aiming.

  • Astrox is NOT an idle game. There are things you can do AFK, but this game requires user input to play.

  • Astrox is NOT multiplayer.

  • Astrox does NOT have AAA quality models and textures. Many are placeholders and will be replaced.

The game will be soon leaving early access. With over 144 updates over 7 years, the journey has been a long one. I could not have done it with the endless support and help from some amazing players and contributors. I am eternally grateful for their years of support and encouragement.
