No drag
Let go of thrust and you keep going until a wall or your own counter-thrust stops you. The speed cap is the only brake built into the hull.
Newtonian dogfighting · in development
Momentum is the whole game.
A free multiplayer space shooter in the line of SubSpace and Continuum. You rotate, you thrust, you drift. Every bullet leaves your gun carrying your ship’s speed, so every shot is a question of where you’ll both be.

Flight manual
Four rules you fly by
Walls give back 73%
Hit a wall and you rebound with 16/22 of your speed on both axes. It hurts nothing but your line. Good pilots bounce on purpose.
Shots carry your speed
Bullets leave with your ship’s velocity added on. Fly at a target and your shots land harder and sooner. Run, and they trail behind you.
One meter
Energy is your hull, your ammunition and your afterburner. Every trigger pull spends a little of your life, so retreat-and-recharge is part of the fight.
Hangar
Eight hulls, eight ways to fly
Each hull keeps the role its SubSpace ancestor made famous and adds one signature move. All of it runs on the same single energy meter.

Modes
Short matches, long seasons, one living world
Arena Roguelite
Waves of enemy factions and rival captains share one map with you. Level up, draft one of three cards that change how your ship behaves, and survive the clock. Die and one card drops where you fell. Fly back for it before someone else gets there.
The open world
Sectors joined by jump gates. Ranks and unlocks that stay with you, ship parts and loot, shops and trading, NPC factions with missions and bosses, and territory that guilds fight over in timed wars.
Team Deathmatch & Elim
Team against team, bounty-weighted kills, last-pilot-standing rounds.

Promises
What veterans asked for, written down
We read twenty years of SubSpace forum threads, subreddit posts and Steam reviews before writing a line of code. These are the commitments that came out of it.
Free, with no pay walls
No subscriptions, no paid power, no supporter tiers.
Classic controls first
Rotate and thrust by default. Rebind every action, or fly with a mouse, a gamepad or a Steam Deck.
Honest player counts
Bots fill empty seats, but they always wear a [BOT] tag and never count as players.
The server decides every hit
Your client never gets to say who died. No kernel anti-cheat, so Linux and Deck stay first-class.
A safe first hour
A short flight drill, a tutorial and a protected queue before you meet veterans.
Nothing that can be taken away
Open, documented formats and a server you can host yourself.

Where the build stands
- Done
Foundations
The deterministic 100 Hz simulation flies a ship in the Godot client. SubSpace’s stock ship settings are imported exactly, and recorded replays verify tick for tick.
- Building
Online dogfights
An authoritative server, client prediction and lag compensation, so two pilots can fight over the internet with bots filling the gaps.

Inkline art pass
The look on this page, in the game: ink-outlined hulls, paper and halftone backgrounds, hand-drawn effects.
- Later
Full combat kit, Arena Roguelite, classic modes, the open world
Bombs, mines and specials. Then the roguelite, ranked play, and the persistent world.
