Battlestar Galactica Online is a free-to-play browser-based MMO developed by European casual MMO giant Bigpoint and based on the popular Battlestar Galactica IP. Players choose the Human or Cylon faction, climb into a Colonial Viper or Cylon Raider (or other) ship, and commence to blasting the enemy into spacedust.
BSGO is set in the time frame of the TV series just after the Battlestar Galactica and the Battlestar Pegasus meet. Branching off from the TV story there, the two battlestars become lost in space, heavily damaged and low on supplies, and from there must return to known space on the other side of the galaxy. Meanwhile, the Cylons are trying to keep the Colonials from finding the resources needed to gather their strength, and press their attack in hopes of destroying the Humans once and for all.
