Aleryos is a free multiplayer space strategy game in your browser, Android and Steam. Build your empire, design your fleet and wage war on two fronts: in space and on the ground.
Two combat systems, two fronts. In space, your fleets: in the Shipyard, you create your own custom, unique ships to serve your strategy. On the ground, your troops: the Pillars, left behind by the Monarchs, send them from planet to planet with no space travel, for ground attacks and expeditions, drone espionage or hacking enemy Sensors. Switch off a planet's Pillars and your army is safe there.
All around you is a full PvE environment: the Errants, Breaches, archaeological Excavations, explorations and public events, with their spikes of risk and reward. You can build your game around it, but other players can still attack you.
Behind it all sits an economy to run: iron, crystal, ether and energy, across up to 10 planets. You join one of five human factions, and your alliance signs pacts and funds its technologies through its members' donations.
Available in 20 languages. Browser and Android: same account. Free, no subscription.
