What the developers have to say:

Why Early Access?

“Since the very beginning of its development way back in 2011, Cosmoteer has been available for anyone to download and play. The feedback from these early players was incredibly valuable, and Cosmoteer would not be anywhere near as good without it. We see Steam Early Access as the natural continuation of this player-centric development philosophy, and we will continue to eagerly listen to feedback from the community and use it to make Cosmoteer one of the best games of all time. Please join the conversation on the Cosmoteer Discord or the Steam discussion boards!”

Approximately how long will this game be in Early Access?

“We estimate that Cosmoteer will be in Early Access for about two years, though that is open to change as the scope of the game changes. Please check out the Early Access Roadmap to learn more. Cosmoteer has already been in active and continued development for many years. Rest assured, we have always and will continue to be dedicated to stability and keeping the game fun and playable at all times. You won't be getting an inferior product if we decide to push back the official launch to squeeze in more awesome features.”

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

“During early access, we are planning to add a ton of additional features and content! Please check out the Early Access Roadmap to learn more.”

What is the current state of the Early Access version?

“"The current version of Cosmoteer is already extremely polished and stable. It will not feel ""janky"" like so many Early Access games, but you may find it a little light on content. Please see the ""About This Game"" section below for descriptions of the currently-implemented features.

Note that during Early Access, it is possible that rare updates may break existing saved games from prior versions, though we will try to avoid that whenever possible, and we will never break your saved ship designs."”

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

“The price may increase during Early Access as new features and content are added to Cosmoteer.”

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

“Cosmoteer already has a strong community of thousands of players who for years have been providing feedback, sharing their ship designs, and making mods. We developers are on the Steam discussion board and Discord regularly responding to questions, suggestions, and bug reports. There's also an in-game feedback tool that can be used to send feedback directly to us. We regularly post updates on the game's development and hold community events such as tournaments and design competitions. There is also an online Roadmap where you can see all the planned features.”

About This Game

A starship builder perfect for fans of games like FTL, Starsector, SPAZ, Space Engineers, Escape Velocity, Avorion, and more.

Design awesome starships using intuitive ship creation tools that are easy to learn but hard to master. Fully customize your ship's shape and floor plan, choosing where to place individual modules including weapons, engines, hallways, and crew's quarters. Your ship's design is key to its survival, and every decision you make will impact its performance in battle. Easily share your designs with others through the Steam Workshop, Forums, and Discord.

A ship's crew is its lifeblood. Numbering from half-a-dozen to a thousand or more individually-simulated people, your crew will pilot your ships, operate their weapons, and carry munitions. How efficiently they operate determines how well your ships will perform in combat. Your crew are autonomous but you can optionally customize their behavior with specific roles and job priorities.

Command your ship or fleet in real-time tactical battles. Combat is physics-driven, explosive, and immensely satisfying. Each module can be individually targeted and destroyed, and whole ships can even break apart into multiple pieces. Target an enemy's weapons to eliminate its offensive capability, destroy its shields to lower its defenses, or go for the kill by taking out its reactor.

Become the most famous "Cosmoteer'' in the universe by battling A.I. ships, taking on contracts for factions, earning loot, and upgrading your own ship while exploring a procedurally-generated galaxy, alone or in online co-op with friends. Then test your ships design and command skills online against other players in multiple PvP battle modes. Or let your imagination fly free in the Creative Mode where you can build whatever you want with unlimited resources.

Still want more? A powerful modding framework and Steam Workshop will keep Cosmoteer constantly feeling fresh with new player-created weapons, modules, and other enhancements.
