Description The main story is random encounters with the BORG! When Voyager warps into a new system there's a chance the Borg will be lurking and attack!
Voyager will ofcourse try and fight back, but its the Borg we're talking about here, so there's not much hope.
Voyager has a limit to the amount of shield power it has. Once its depleted it will start taking damage. Shields will recharge in time though so don't panic. (See the shield meter in the top left of the screen).
