Bigpoint's browser MMO known as DarkOrbit prior to last month's space drone microtransaction brouhaha, you're not alone.
According to the company, though, lots of people have heard of the game, which launched in 2006 and is currently celebrating its fifth anniversary. Bigpoint claims a community of over 65 million registered players, and a news release says that DarkOrbit is "the most popular and biggest space game worldwide."
DarkOrbit is a 2-D flash game that puts players in control of a spaceship while working for one of three corporations.
