Players will be able to make a new Captain appropriate for the timeline of the original Star Trek, investigating problems and exploring frontiers that were certainly quite new at the time. The expansion also features classic Star Trek voice talent to make the game feel just a bit more authentic. Unfortunately, we’re all still traveling through time at a linear pace, so you’ll have to wait a bit longer before you can also go back in time to a slightly less far-flung future.
