Deepolis is a 3D Action MMO Browser Game quite different from other browser games because of its game world. Earth has been destroyed and flooded by water. Players take the roles of submarine commanders who must steer their submarines trough the endless depths of the dark oceans. Armed with an assortment of weaponry, they will fight other players, deadly sea creatures like giant kraken and other dangers among ocean rifts.

When the game starts, players must first join one of three warring factions: Scion, Nauts, or Jafnhar. Within the first 5 levels new players can switch factions at any time which is a good thing for beginners to decide which faction to go for: Nauts are a loosely organized coalition of anarchists such as soldiers, traders and researchers who survive in the ocean mainly because of their achievements in nanotechnology. The Scion are masters of photovoltaics and biology for the purpose of producing oxygen. They feel not comfortable to live in artificial shells of plastic and metal like the other factions and build marvelous sub aquatic parks. The third faction, the Jafnhar, are tightly organized and all aspects of their life is influenced by the military. Nuclear technology and oil production were the main reasons for them to seek out deepest trenches of the ocean as their area of settlement. The buildings of their cities can be spotted miles away in the murky abyss by the red lights of the guard towers.

The gameplay of Deepolis is really fun and mainly consists of collecting floating wreckage items and defeating enemies by doing quests. With the valuable Helix or Cel the players can go to the trade market and buy cool stuff like powerful sonic cannons, multiple torpedoes or naval mines. While doing all that the graphics of this deepsea browser game are really impressive: fish, sharks, crabs, plankton, and other marine life produce a realistic looking underwater world. Although this beauty is free at first, real power come at a price, naturally. As in most other Big Point Games one can buy a special currency that will give you advantages over the other players. For most weapon upgrades and other purchases the valuable "Helix" is needed. If a player upgrades to a premium account he will get from 30k to 75k of helix.
