About Phantom Signal — Sci-Fi Strategy Game

✦ AI summary

Build and defend your space station while managing resources, upgrading systems, and battling uniquely challenging enemies across multiple star systems to uncover the source of a mysterious signal. Master strategic base construction and tactical defense mechanics while competing on leaderboards and hunting for achievements in this story-driven space survival experience.

A drifting space ship wakes up due to unusual interference in space. Almost right after this, an unknown enemy attacks the ship. To withstand this new threat and reach the source of the signal, the ship’s command module activates an industrial fabricator, which you take control of.
Your tasks include constructing an energy grid, procuring resources, upgrading the ship and destroying enemies.
Every enemy type has its own peculiarities. They have their own strengths and weaknesses.

As you approach the phantom signal, you encounter missions that demand a strategic approach to constructing and defending your base.

The universe won’t reveal its secrets to the first person that comes along. You’ll need to travel a long and complicated path through multiple star systems to find the source of the signal.

Invite your friends and compete for the top spots while completing missions!

We use Steam Leaderboards and Steam Cloud to make this happen.

If you complete the game faster than us, get one of 52 achievements!

Trading Cards will be available in the game after Valve lets us activate them.

We’re also planning on releasing 3 DLCs for fans of the series and launching PvP tournaments ;-)

Key features:

  • Incredibly beautiful deep space
  • A plotline, main and sidemissions
  • Non-linear approach to completing missions
  • System for researching and upgrading unique abilities
  • Varied enemies with adaptive AI
  • Ability to select a comfortable game speed for you
  • Excellent replayability (potentially)

Kind of addictive play. Story is very predictable. Also pet pev - when you supposedly swap sides you are still fighting the same ships as before. One last thing - I hate escort missions.

The graphics are basic but the gameplay is fun.
Not recommended Apr 1, 2025
It's not a very good tower defense type, despite its novel twist on the genre. It's actually a spiritual successor to an old flash game over a decade ago, called The Space Game. There's a massive lack of quality of life features such as chain placement, key shortcuts thus requiring manually clicking absolutely everything save for time pausing, and general play testing. In particular there's the gain 100% of minerals when recycling any Lv1 structure. This upgrade alone allows for cheesing of most enemies and scenarios. Any enemy can be infinitely juggled by recycling any structure. Objectives are sometimes vague and you're liable to lose progress because you didn't know the dev was going to throw a death wave at you. I still played anyway out of mild boredom and nostalgia. For anyone curious, go download the Flashpoint Archive and look up the "Space Game" from The Casual Collective. The original game had more polish, better visuals, music, and even a story despite the fact it's really just a mining company looking to make a profit

Boltgun 2 price: buy the sequel, or the cheap first game?

The Boltgun 2 price has no cheaper route on launch day — our record shows one listing, unmoved since September. The first game is the bargain, but a smaller one than it was.
