Aleryos is a free-to-play multiplayer 4X strategy game played in a web browser. Players build and specialize a galactic empire through resource production, research, colonization, exploration, espionage, diplomacy and warfare. They design and personalize custom ship models to create unique fleet compositions based on their strategy, fight both in space and on planetary surfaces through the Pillars, join alliances with shared technologies and bonuses, and take part in PvP, PvE and recurring competitions. When enabled, Galactic Catch-up reduces costs and completion times for empires behind the leaders, helping newcomers join an established universe. Aleryos is available in 20 content languages across 25 locale variants.
