About

Take control of a submarine in this underwater MMO simulator. Navigate a 3D ocean realm by completing missions and battling other players or computer-controlled targets. Earn experience points to level up your vessel and unlock upgrades. Play solo or team up in browser-based matches. The game runs in a web browser with no install needed. Clan support lets groups coordinate attacks or tackle shared objectives. Bigpoint launched it in 2008 as a free-to-play title with optional microtransactions. The blend of strategic combat and progression mechanics kept it active for years. Some players still run clans focused on PvP rankings or resource gathering. The simple controls make it easy to jump in but harder to master.
