What the developers have to say:

Why Early Access?

“So far my focus has been on the core gameplay mechanics of the combat and underlying systems that make up the game, I feel early access is the perfect place to maximize the potential of the game by interacting with new players and collecting their feedback, this will allow me to improve and evolve the gameplay whilst adding new mechanics and extra content.”

Approximately how long will this game be in Early Access?

“The plan for the EA stage is approximately 1 year long, this is not a fixed timeframe. New ideas and player feedback might mean this is pushed back in order to meet player expectations.”

How is the full version planned to differ from the Early Access version?

“The intention for the full version is to expand with greater number of features whilst refining the current ones. The currently planned features are:
-More base environments,
-More Ship components and content,
-Added Base and base types
-Ability to write own mission briefs and story narrative to player missions
-A storied campaign
-Improved Ship Component Models and Textures”

What is the current state of the Early Access version?

“The current state of Parabellum Galaxia has VR and Desktop support for the Ship Builder, mission builder, Fleet vs Fleet battles. Modifiable ship systems and full physics based motion are implanted, along with initial implementation of fast bombers and hangers. Player Ships and Missions can be shared giving the opportunity to expand the mission and types of missions beyond what i am capable of producing myself. Support for these player ships and missions in future game versions is not guarantied. A streamlined scenario builder allows for quick missions.”

Will the game be priced differently during and after Early Access?

“The base price of the game will increase with full release.”

How are you planning on involving the Community in your development process?

“By letting the player experience the full content that the game has to offer it allows me to collect their feedback to improve the game whilst also focusing my development targets. Making sure I steer my development in the areas where there is greatest interest.”

Update Notes

Once you've tried the demo, feel free to request access to the playtest! The playtest features limited player numbers but has added features including the mission builder so you can make your own content with your own ships! The purpose of the play test is to debug and try out new features, when moving to Early Access the playtest will be limited to new features and testing multiplayer.

See the discord and community forums for news on the current developments or just ask me and i'll get back to you when i can!

About This Game

Parabellum Galaxia is a highly tactical, approachable, 3D Space battle simulator where you command fleets of bespoke ships in PC or PC-VR against AI or Online opposition. The sandbox nature gives players the ability to create their own ships and missions using the inbuilt building tools or you can use premade and community content playing against AI or Online.

The use of newtonian physics and fully modelled ship systems ensures that your newly created ships perform as designed. Facing off against Online opposition both fleets can contain ship and fleet designs neither has seen before.

Adapting your fleet and playing to your fleets advantages are key to dominating your opposition.

Command your Fleet in VR

  • Command your fleet using the approachable VR interface
  • Configure individual ship systems and behavior's to maximize their potential.
  • Even the lightest ship in your fleet is no light weight. Ships carry their inertia and change in directions are not instantaneous. This allows for a heavy tactical feel to your ships where your battle formations may decide whether you are victorious.
  • Plasma turrets reduce in effectiveness at range, and missiles can be intercepted in-flight meaning sometimes the only way to destroy your enemy is to get in close rather than standing off.
  • If your fleet is small and fast, hit/run/recover/repeat may be the tactic of the day. Or do you slug it out with your heavy ships against theirs in close range. The choice is up to you.

Design your Ships

  • Engineer your own ships using the VR Ship Builder. Shape the outline and size of your ship, place the internal and external components and paint the ship in your own color scheme.
  • The performance and effectiveness of your designs are automatically calculated for motion, ship and damage systems.
  • Decide where you want heavy armor and where you need little armor at all. If you place all armor on the top the enemy will know to try to go beneath you, but then again your ships are more nimble because of this and means you can have more ships in your fleet.
  • Ship Systems such as crew allocations, power, weapon recharge and reloading are fully simulated and automated. Move ammunition closer to your missiles launchers and ensure faster reload times, but the enemy may see how fast your reloading and target weapons near your launchers.
  • Use these ships in your own missions, share them with your friends or keep your designs to yourself.

Newtonian Flight Physics

  • The inbuilt flight model calculates the thrusters to apply to go in a given direction and the counter thrust required to ensure target destinations are not overshot. This ensures ship motions are handled realistically as if its a real spaceship.
  • This can be taken advantage of in combat. If the enemy is circling you, attack those thrusters to ensure they can no longer do this.

Voxel Based Thermal Damage System

  • An advanced voxel (cube based) damage system overlays your ships where adjacent cubes transfer heat and damage is propagated.
  • This system ties into the ship systems, so when engines are active that part of the ship heats up. Running the Reactor at 100% may eventually lead to component overheating and even system shut down unless your ships are adequately cooled.
  • This model helps ensure ships have their advantages and disadvantages in design correctly modelled.

Create your Missions

  • Create and Share missions and scenarios built using the Mission Builder.
  • Mission types such as destroy all, survival, reach target, guard target and more are supported. Player fleets can be preset or player defined with a mission mass limit.
  • Create the battles you want to fight.
