Hey everyone 👋

I'm the Community Manager for Kardaviik, an upcoming 3D factory automation game set in a voxel asteroid belt.

We're currently running a free, open playtest on Steam, and I'd love to invite the r/spacegames community to give it a go!

In Kardaviik, you can explore procedurally generated asteroids, mine resources and build sprawling factories across the asteroid belt. There's no need to stick to flat layouts either, as you can build in every direction and expand your operation however you like.

You can explore and build solo or team up with friends!

We're actively looking for player feedback, so whether you've got suggestions, run into bugs, or just want to show off something you've built, we'd really appreciate you getting involved!

Thanks for checking it out, and feel free to ask me anything about the game! 😊

Hi, I'm Justin, a space enthusiast making my first solo game, StellarForge.

I'm exploring spacecraft construction that begins with the machinery that makes the craft possible: a huge load-bearing spine and propulsion interfaces, with habitats built around them. Fighters would use compact chassis instead.

The images below are early Blender grayboxes, produced with AI-assisted Python modeling scripts—not in-game flight footage or finished ships. The proposed colony backbone is 200 metres long. This pass is about proportions, modular anchors and engine interfaces; materials, detailed systems and engine-side fit are still being worked on.

The wider game is a space colony-building project. Working systems and prototypes are at different stages, and the complete colony-to-spacecraft journey is not finished.

I'm looking for colony/space-game players interested in following early builds and helping spot confusing interactions and bugs. Join the Discord for development updates, feedback and test-build announcements: https://discord.gg/K3MUpZjD4

This is a tester-interest invitation, not a promise of immediate access. Honest criticism is welcome. Would you prefer building freely around an exposed core, or selecting a chassis with stronger constraints?

Hey everyone! Orbital Defense Idle is a sci-fi incremental tower defense game where tarot cards influence the fate of the battle!

I just launched my open playtest on Steam this week, its be really cool if you checked it out: https://store.steampowered.com/app/5027850/Orbital_Defense_Idle/

Thanks!

• Ships are real engineering. Sectioned armor, separate energy and heat, weapons matched by size, type and mount, and signature abilities for each ship line. The same hull fitted two ways plays like two different ships. Now have 50+ uniques!
• Every warship is a living colony. Hundreds of crew eat, sleep, work shifts and man battle stations. Fires, decompression, permanent injuries and mutiny inside the hull decide how the ship fights outside. You can control each of them!
• The frontier runs without you. Three powers besiege ports and rebuild their navies, markets follow real supply and demand, and pirates raid convoys. Every side you take moves the front line. Too much to describe in one line ;)

I am recruiting players for first closed playtest in late October. Comment or DM if you'd like in!

The game is inspired by EVE Online, but with three key changes:

• Less grinding, more strategy: Resources are regional, not everywhere. No single faction can mine or manufacture everything it needs. Survival depends on trade, alliances, and diplomacy, not repetitive mining runs.
• Building and community come first: Found a nation. Build a shelter even with limited resources. Claim and develop planets, down to small personal touches that make a place feel like home. The galaxy starts as an empty void, every station is built by players, from nothing.
• Other players stories are visible: See who’s in a system or station right now. Understand the supply chains that keep a faction alive, and who holds which role in it. Read what’s driving other players and use that for more complex diplomacy.

Self-promotion, since I'm the one who made it.

VonN starts you with a single von Neumann probe in a 10,000-star galaxy shared with other players. Light speed is the hard limit for everything. Your commands take 4 seconds per light-year to arrive, and what your ships see takes the same time to get back, so you're always working from old information.

It's free at https://VonN.io with no signup. I'm running the first real test right now and want to hear what space game fans make of it.

It's free, and it stays free. Cosmetics come from a Signal Cache you can open every 4 hours, and duplicates turn into shards. After the test, caches open with a short ad you pick to watch, and the end of a run plays one more. Paying $4.99 once turns ads off for good. Nothing is pay-to-win, and nothing is for sale right now.

I'm collecting feedback in the #vonn channel on my Discord. https://discord.gg/VzHpyQfV4q

Claude wrote some of the code, and I did the hard parts.
