HUD (Heads Up Display)

You can see vital information about the current situation in these regions of the game screen:
(1) -- Galaxy radar is provided by friendly planets with Communications Centers. Markers indicate the positions of planets, stars, and spaceships: green, yellow, and other colors, respectively. You can press M or click on this small display to expand the display to fill your screen.
(2) -- Your rank is display along with current progress to next highest rank.
(3) -- Spaceship type and damage level
(4) -- Active weapon: if the weapon requires an ammo supply, it is shown as a tally underneath the weapon name
(5) -- Pointer to nearest star (yellow)
(6) -- Pointer to nearest planet (green)
A message log is shown at the bottom right corner of the HUD. As the battle wages on, you will receive progress messages here from the parts of your faction's war machine. Most recent messages are displayed at towards the top, leaving older messages to drop off below.

Game play

You begin with either an invasion fleet (1 x Fighter + 4 invasion Freighters) or a single occupied planet.
To colonize planets, you must land on them when they are unoccupied with your Fighter. The landing will plant a beacon, starting the flow of Freighters and raw materials sent to construct facilities on the planet.
To win, you need to destroy all enemy production, combat facilities, and spacecraft.

Landing on planets

Before colonization can begin, you must land on a planet to secure your colonization beacon. Approach the planet at slow speed and rotate the craft to face outwards from the planet's center. A landing speed indicator will be shown as you approach the planet. Failing to correctly orient and slow the Fighter will destroy it on contact with the planet's surface.
When you land on a friendly planet, your weapons will be rearmed and your ship repaired.
Note: you cannot land on stars. Fighters are affected by gravity from both planets and stars.

Landing on a friendly spaceport

Much like landing on a planet, you must approach the spaceport slowly and aim for the center of the spaceport to trigger the docking sequence. Once this is achieved, the spaceport will catch your fighter craft. Rearming and repairing aboard the spaceport is much faster than on a planet surface.



The standard energy weapon supplied by the same power plant that drives a spacecraft's propulsion system. Damage: 1 per hit

Heavy Cannon

Focusing the emitters of the standard cannon allowed us to create a weapon that delivers twice the energy per projectile. Damage: 2 per hit

Cluster Rocket

Packed with explosive shells, this unguided rocket can deliver a bundle of 20 to the recipient for maximum destruction. Damage: 1 per hit x 20 shells + 0.5 impact damage

Homing Missile

We have refined a biological seeking intelligence that is installed into every mass-produced homing missile: a highly destructive weapon. Ensure your targeting system has locked onto an enemy before firing. Damage: 6 per hit

Laser Bolt

Fast discharge ultra-capacitors have enabled our technicians to build a devastating laser weapon into a small space. Damage: 30 per hit, ranged



The backbone of an offensive fighting force is the standard GHX-12 Fighter craft armed with a rapid-fire cannon. Fighters can lay claim to unoccupied planets.

Transport for raw and finished materials is provided primarily by Freighters. They carry the capability to speed up construction of essential fortifications and facilities. Freighters are the only craft capable of constructing a Planetary Base (PBase).

A typical planet with a full complement of facilities.


A Planetary Base (PBase) provides a planet with basic production and mining operations. It can harvest and store raw materials on the planet. It can construct a Communications Center and a Planetary Lab. It also provides defensive weapons, allowing the planet to defend itself from attackers.

A Planetary Colony (PColony) is the most efficient way for a planet to produce finished materials from raw materials. It can construct spacecraft and other facilities; its operation is critical to the maintenance demands of a planet.

Galactic scanners installed in the Planetary Communications (PComm) allow empires to track precise locations of other worlds. A galactic radar display is active when your faction owns at least one functional PComm.

The orbital Spaceport and its facilities allow the Fighter craft to be swiftly repaired and rearmed. As it is the first point of defense for a planet, it is heavily armed and armored.

Gameplay inspired by Gravity Well v2.2, the planetary conquest game by David H. Hoeft of Software Engineering Inc. Celestial Combat owes its existence to this classic 1995 masterpiece.
