How a browser space strategy game plays
There is no client and no install. You open the game, give your orders and close the tab. Mines keep producing while you are away, buildings and research finish on their timers, and fleets arrive when their flight time says they will. A session can be five minutes to queue the next upgrades, or an evening spent planning a raid with your alliance.
The core loop
- Economy. Metal, crystal and deuterium mines, powered by Solar Plants and Fusion Reactors. Storage decides how much you can bank.
- Research. A technology tree that unlocks faster drives, stronger weapons and shields, and bigger production bonuses.
- Fleet. Cargo ships to haul, probes to scout, warships to attack and defend, Recyclers to harvest debris.
- Expansion. Colony Ships settle new planets, and your Astrophysics level decides how many you can hold.
- Politics. Alliances, wars, non-aggression pacts and a public highscore ladder.
- Deep space. Expeditions to position 16, where what you find scales with the fleet you risk.
Strategy measured in minutes and hours, not reflexes
Nothing here depends on how fast you click. Flight times, build timers and research queues turn every decision into planning. Who do you scout? When does your fleet land? Will it be home before the enemy's arrives? The best players win by timing, not by speed of hand.
That makes defence a skill too. Before you log off, you fleetsave: you send your ships on a mission that keeps them away from home, so an attack finds an empty planet. It is the single most important habit in the genre, and the fleet guide explains it.
