It's a huge expansion of the Privateer Remake featuring most of
the ships from WC1 to WC4 (and more), all the systems in the known WC
galaxy, some fleet-control ability (buy a Drayman and turn it into a
mini-carrier!) and new mission types such as escorting passenger ships or coordinated strikes.
If that sounds like your thing, you can grab the 184 meg starter pack here. This is a test release, so players not interested in encountering and reporting bugs should probably wait for a later build. SpiritPlumber would appreciate feedback.
