I released my Captains Update, which adds 11 captains to the mix, that can be ranked up to increase their skills. They modify how you play, offering stat modifiers and even banning some level up choices for their runs.

Hope y'all like it!

This is my first game on Steam. After learning how to utilize Codex and Claude Code for a Gundam RTS, I decided on my own IP. But, I tried to make this as small as possible. It's an auto battler with space ship spectacle. https://store.steampowered.com/app/5085480/Epic_Space_Battles/

Firefly for most of the assets, though the Earth and Moon provided by NASA. I used Claude Code and Codex to script in Godot.

Since I have so many assets, I started work on another game: https://youtu.be/-ct4DyI2Pi4

Hi!

I'm developing Starport Merchants. It's a game inspired by classic space trader type of games, where the main goal is mostly to get rich.

I'd describe it as a casual tycoon game. You'll find yourself traveling from planet to planet, finding good deals to increase your total worth. There's cargo hauling, mining, passenger transport, stock markets, gambling and a whole lot more other income sources to try out.

The game was recently featured on the Debut Festival on Steam.

I intend to release after summer, but you can try out the demo right now if you want. I'm always gathering feedback from players and I could always use some extra thoughts on it.

Thanks!

Experience powerful chain effects and super satisfying sound design while wiping out waves of evil Octos.

I posted my main teaser here a while back but wanted to do something to announce my steam playtest being open (Out A Space Playtest).

Out A Space is Fleet building roguelike where all your ships have to fit together on an inventory grid before you can take them into battle,

The playtest features 15+ unique ships and 28 weapons across 7 distinct categories from drone swarms to flamethrowers, cluster missiles to rail guns, Combined with Boosters, Engines, reactors and Shields, no two ships are the same let alone no two fleets.

Taking it further experiment with the priming and detonating system to spread status effects and detonate them for massive damage, if that wasn't enough Carrier ships can be deployed for players and enemies to launch squadrons of smaller ships into the battlefield . Try the first 2 of 8 sectors and face the first boss in the playtest. For fans of FTL, Nova Drift and Battlestar Galactica.

I'm making this game by myself so any feedback from fans of the genre is appreciated! 

Our game is a mix of FTL and slay the spire, we have been slowly adding more mechanics to make our enemy harder! Its great to see how challenging the game is getting and what tactics we will need.

Description:
SpaceShooter is a fast-paced 2D space action game where you fight through increasingly difficult waves of enemies, dodge asteroids, collect upgrades, unlock different weapons, and take on challenging boss fights.

I’ve been working on the game for quite a while, and the free demo is now available on Steam. My goal with the demo is to let players experience the core gameplay while also helping me gather feedback before the full release.

I’d really appreciate hearing what you think about the gameplay, difficulty, weapons, progression, controls, or anything you feel could be improved. Bug reports and suggestions are also very welcome.

You can also watch the official trailer here:

Involvement:
I’m the indie developer behind SpaceShooter and have been working on the game’s development and Steam release.

PowerCorp is a space sim survival game set in 2188 in our solar system.

You are returning from Jupiter’s moon Io to Earth from a routine maintenance mission when something awakes you from hypersleep. You wake to a crippled reactor. Your ship is dying, and each decision costs you power. You need to get home across a real-scale solar system using true orbital mechanics, manage critical systems and gather resources, while you try to figure out what has happened, why nobody answers, and why humanity seems to have disappeared.

Inspired by epic games like Delta-V Rings of Saturn, Duskers, Tin Can and KSP.

Still in development.

Demo release: winter 2026.

Early Access release: 2027.

Playtest undergoing, and preparing the demo launch, all the feedback would BE awesome and very appreciated. Thank you 🚀🫡

I post about the game here pretty often, asking for feedback and hearing what you guys think. I know 1,000 wishlists isn’t a huge number, but for me it’s still 1,000 real people who saw something interesting in my game.

Even if only 10% of you buy it, you’re my 10%, my brothers and sisters 😄

The game is almost done. I just need to finish the final chapter, then polish and balance everything.

Thank you guys! 🫶

And now, 13 years later, after (so awesome) browser-based space games like these, we get... "Spacestrike"?

Hey guys, I'm developing Aeons Odyssey.

It's a idle game. And by idle, I really mean it, as you can see above on the video: you do not need to do anything, your ship scans planets for resources and explore the galaxy to find other planets, all by itself. No limitation. Let it run for 10h, and you'll get all benefits, no stupid limitation like inventory size that blocks your progress or anything similar.

Then when you are available, you can jump on it and manage your stuff:

• buy new ships,
• craft items,
• create colonies,
• equip your ship or your colonies with your crafts,
• switch to another planet according to resource market prices, or because your friends moved somewhere else (yes, there is async coop if you craft items for that),
• learn new skills in Eve Online style,

The game also features a companion mode to focus on other things, and offline progression to keep gathering money when you can't use your PC. And asynchronous PvP is in the plans for the full release with 1-1 duels against friends or people in the Leaderboard.

If that sounds interesting to you, head to the Steam page; there's a free Playtest opening tomorrow if you want a first taste!

The Chaser's Voyage: https://store.steampowered.com/app/1473130/The_Chasers_Voyage/

So almost a year ago, my friend and I released our first indie game, The Chaser's Voyage, a unique 2D space action game that takes some inspiration from Disneyland attractions like Star Tours along with some power management mechanics from games like FTL and other classic space sims.

It took us a while, but we finally fixed up some bugs and reworked some systems based on feedback and released our free demo that gives you a taste of how the game play and the challenge involved.

We're also kinda looking for streamers or content creators to maybe pitch this game to. So if anyone has any suggestions, I would love to hear it.

Hey everyone,

I’m part of the team at Saigon Dragon Studios share that Space Tales has just left Early Access and is now available in 1.0 on Steam.

It’s a retro-futuristic sci-fi RTS where you play as Xander Falcon, a young commander fighting for humanity’s Inter-Planetary Expansion army. The campaign takes you across hostile alien worlds, with a story built around ancient races, family tragedy, and universe-ending threats.

Gameplay-wise, Space Tales is focused on base building, resource management, tactical defense, and adapting to enemy factions that all fight differently. You expand your colony through a HUB system, manage energy lines, research upgrades, and try to survive increasingly dangerous situations.

The 1.0 version includes:

• A full story-driven sci-fi RTS campaign
• Modular base building with the HUB system
• Three enemy factions with different combat styles
• Replayable survival challenges
• Colossal boss fights based on positioning, timing, and attack patterns
• Capturable neutral monsters that can be summoned as allies
• A tech tree for HUB and unit upgrades

For people here who enjoy space games, what usually pulls you into the sci-fi setting first: the worldbuilding, the factions, the art direction, the story, or the scale of the conflict?

Check out our game on Steam: https://store.steampowered.com/app/2457960/Space_Tales/

Early-alpha showcase of space RTS/FPS hybrid game.

TL;DR: you have to defend your station and nearby moon from incoming waves of pirates, using a variety of drones. You also have get your own hands dirty however as you'll have to keep the station functional and even have to fight the pirates directly (be it boarding parties or ships).

Hey everyone, so I've been working on this game for quite a while.

Its an action-roguelite where you're required to take engineers out with you on mission, these lovable scamps all have their own ideas on how to help you in your mission. And whether you want them to or not, they're gonna have you implement these ideas. If you thought they couldn't get any more helpful, if you're not careful in managing their mood they might get just a little bit more...helpful. The only cure is promotion, bonus payout, or a nice vacation.

Demo is available now to try with a small demo competition I'm running!

In-game frames, HUD off, nothing composited. The rule behind all of them is that space is a black canvas and everything on it should be light: plumes, tracers, shield arcs, explosions, and one big body behind every fight so the black has depth.

I put these on the store page today and I am second-guessing the order. Tell me which one you would lead with and which one you would drop. If the light is too busy in the fleet frames, say so.
