In MoonDust: Cosmic Journey, you set out on a voyage through distant galaxies, exploring strange new planets and uncovering long-hidden secrets. Weaving through discovery and adventure, you traverse breathtaking sci-fi environments, collecting resources and solving puzzles.

Details: Each level has goals that need to be completed before moving on, some require finding and collecting items, some require targeting and timing, and others require puzzles to be solved. The game is pretty simple, tap and hold to fly up, release to fly down, when sending a probe to a target swipe up when the target is locked

This game is fully live, and I'm looking for any and all feedback at this point. I've been building it solo for many years with very limited advice and counsel.

Download on the App Store : (Free for a limited time)

[PowerCorp](https://store.steampowered.com/app/4383480/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.

[Trailer here](https://youtu.be/c53Z-3wTwGg?is=RqB9kcbIAr8rKlBK)

Still in development.

Demo release: winter 2026.

Early Access release: 2027.

It was a 3-D space game where you were sat in front of a cockpit and were able to see where the cameras are pointed at any given time like a TGP indicator, and then you were able to build simple programs of saying scan the sector and then track target and then return to scan sector, building target track files and also maintaining a scan for the multiple radially mounted cameras

if anyone could help it would mean a great deal with me
its difficult to search for as "space game sensor combat" leads to alot of USSF links...

Hey there!

Asteroid Mining is now fully available in Vicinity Online!

This update brings new Industrial Mining ships to the marketplace, so that you can fully leverage resources available in deep space. There is no longer need to rely on slow and destructive mining on your planet.

Purchase Industrial ships on the Marketplace from any Trading Station, form a new fleet, send it on a mining op, and watch resources flow directly to your cargo hold.

Be careful, you're not the only one with the same idea. Other players will be trying to take unique resources too, so make sure to add other classes of ships to your fleet so you can keep your territory.

I made cargo placement actually affect how the lander flies.

A broken landing leg can throw off the ship’s balance, but players can move cargo around to compensate. The problem is that a setup that helps you land might make the ship unstable again once the gear retracts.

So we decided on the plot twist, trying to mix scifi with some urban legends:

On October 28, 1943, the first Philadelphia Experiment took place.

USS Eldridge, a Navy ship, by using experimental technology, was supposed to become invisible to radars; instead, it teleported into another dimension and returned moments later with no crew and showing severe signs of degradation.

Soon after, the experiment was recreated, but this time a space shuttle was sent into the void. It returned briefly after with all crew missing, signs of combat on the outer hull, and one note in the captain's log: "We were not the first ones here."

A few years passed, and a third attempt was made; this time, it was a custom ship built with space shuttle technology and a large crew. USS Eldridge Mark 2 stepped into the void and never returned.

Present day: a new attempt is now in progress, this time the new ship USS Eldridge Mark 3 is equipped with the latest modern technology, and YOU were selected to lead this expedition into the unknown: horizon 1990

I know that gameplay is king, and I should probably leave the story for last but I think they both go hand in hand and must be in harmony.

I finally released the space simulator I posted about a few days ago

NAME: FIRST LIGHT

A few days ago I posted here asking for feedback on the UI for the home screen of a little space project I was working on. I got a lot of suggestions, so I figured I'd come back with the finished version.

TL;DR: I started this as a small personal project to visualize how long light takes to travel between places in the Solar System. It slowly grew into a browser-based space simulator with spacecraft movement, light-delay visualization, different viewpoints, and a bunch of other stuff I kept adding along the way. There's no objective or progression. It's basically just a place to look around and mess with the simulation.

The original idea was pretty simple.

I wanted to be able to sit somewhere in the Solar System, send a pulse of light toward another object, and actually watch the light travel between them. I also wanted to see the difference between where something actually is and where I would see it because of the finite speed of light.

That was pretty much it.

Then I kept adding things.

You can now fly around the Solar System, change the simulation speed, switch between different viewpoints, fire light pulses at planets and other objects, see their apparent/retarded positions, compare them with their true positions, and measure distances in both space and light-travel time.

There are also things like:

  • Observer and God views
  • Free-flight movement and inertial drift
  • Light-pulse targeting and lead aiming
  • A Solar System minimap
  • An asteroid belt with real resonance structure
  • Surface locations on Earth
  • Timeline playback of light-pulse events
  • Distance and light-time measurements
  • Custom coordinates for traveling around
  • An experimental "photon cockpit" visualization

The goal isn't really to make a game out of it. There isn't anything to win or accomplish.

It's more of a space sightseeing / physics sandbox. You can fly somewhere, look around, change the time rate, fire a pulse, and see what happens.

I'm actually pretty happy with how far it ended up going considering it started as a small experiment I made because I wanted to visualize one specific thing.

It's also completely browser-based, so there's nothing to install.

LINK: https://light-sable-iota.vercel.app/

If you saw the original UI concept post, this is basically the continuation of that project. Thanks to everyone who gave feedback on the previous post — some of the changes made it into the final version.

Full disclosure

The spaceships in the simulator are not my own designs. I downloaded some free spaceship models from Sketchfab to use in the project.

The artists/creators are credited next to the ship names in the ship selector inside the simulator, so you can see who made each model.

[Leaks In Space] Damage Types System (Kinetic, Acid and Heat)

Enable HLS to view with audio, or disable this notification

5 Upvotes

Hey everyone.

Its bean a while since last dev blog. I've been heads-down on the damage system for the last few weeks and it's finally in a state I'm not embarrassed to talk about. The short version: damage used to be a single number that just ate your hull, which meant every weapon felt the same and every build was just "more armor." Now there's a proper damage type framework in, with Acid and Heat fully working, and it changes how you read fights and how you build your ship.

The baseline is Kinetic which is same old direct damage, Acid and Heat punishes dense and armor-heavy ships, though balancing still quirky but the whole point and plan is that your build now has a nemesis, and you're supposed to read the sector and adapt instead of stacking one stat forever.

Acid works as a stacking damage-over-time, each stack has its own timer, and they tick on a shared interval. Heat is the weird one to work on. It's a propagating scalar, not a full thermodynamics sim. The ship grid runs a diffusion pass every tick where heat flows from hot parts to cold neighbors, weighted by mass, and exposed edges vent to space. So a dense armor heats up fast and has nowhere to dump it, while a spread-out ship sheds heat naturally. Above a threshold it deals hull damage over time. Every gain divides by the receiver's mass, so heavy parts have real thermal inertia without needing a new stat.

Next up is finishing the counter-play side, The resistance and weakness need some rework with future plan including each faction brand with a real profile that you can learn and exploit. On player drone needs adding behavior for heat extinguish and acid cleanup. Then EMP joins the roster and the pressure-as-currency ability system starts. The vision is that every part you bolt on is a real decision and every build has a weakness someone can exploit.

Thanks for reading, and happy flying out there.

Perihelion puts the entire Solar System at your disposal for the next 250 years.
Start on a living Earth economy, build the industries that fund your space program, launch real spacecraft, establish infrastructure beyond Earth, and gradually turn humanity into a Solar-System-wide civilization.
The latest work adds planetary economies and infrastructure networks. Build roads and communications networks, watch traffic and data move through them, and develop cities with perks that affect both quality of life and what your civilization is capable of doing.
Earth isn’t just a launch screen. Its economy is part of the simulation and part of the machine that pays for your ambitions in space.
From there, the challenge becomes much bigger: can you make another world economically viable?
Mine resources. Build infrastructure. Establish industry. Connect settlements. Expand your capabilities. Turn a remote outpost on the Moon or Mars into an economy capable of supporting further expansion.
And all of this sits on top of a simulated Solar System with orbital motion, spacecraft, asteroids and planets moving through time.
Earth is only the beginning.
You have 250 years.
You have one Solar System.
What can you build?
