While it's not even in the alpha stage as of yet, BSGO is reportedly looking solid, especially for a browser-based title. The primary focus of this space-shooter MMO is the PvP conflict between human and Cylon forces. Players should expect to handle ships from the series (such as the Viper), but Bigpoint is planning on creating new spacecraft unique to the game. Each ship will handle differently, forcing users to adapt on the fly or die.
Although the main stage of the game is the struggle to control systems (and their precious, precious resources), you'll be able to explore areas on foot, such as the titular Galactica, although this is mostly for atmosphere and storytelling. For players worried about the game's microtransactions model, Bigpoint promises that everyone will be able to experience the game from beginning to end without being forced to spend a penny.
