Dark Orbit

Players must control a spaceship to battle against evil non-player characters and other players. If a player defeats an enemy, they will be given rewards, which they can use to upgrade their spaceship and its equipment. DarkOrbit is a free to play game with an optional monthly subscription called Premium that adds various benefits. An additional in-game currency called Uridium can also be purchased to buy Elite items. The game was originally playable within a web browser and did not require any download, while in the wake of the discontinuation of Adobe Flash Player, it was made available on Mac/Windows/Linux platforms with a standalone launcher.

At the start of the game, the player chooses between three companies : Venus Resources Unlimited (VRU), Earth Industries Corporation (EIC) and Mars Mining Operations (MMO). In the story, one more company exists (Saturn Autonomous Technology) but not for the players. Players are teleported to the home map to begin quests from Mission Control.

DarkOrbit started as a closed beta test, in which over 80,000 players participated. They later on passed into an open beta phase. Finally, on September 1, 2005, the game passed into the subscription phase, which is expected to continue for the entire lifespan of the game. Currently, there are 300 million registered accounts.
