We've made a few changes to The Ship packages on the Steam store, which I've outlined below.
The single player game was previously sold as a separate package, as well as being included in the Complete Package. However, a number of users reported problems with the single player as a standalone game and as we were unable to resolve these issues, we've remove the option to buy the single player by itself.
Anyone who purchased the single player game without the multiplayer game, now should be able to claim the Complete Package for free (which should resolve issues playing the single player).
If you have any problems with this, the please leave a comment here.
Previously, if you purchased the Complete Package, you received additional gift copies to send to friends. While we understand that some people made full use of these, our stats show that most people didn't.
For this reason, we've removed the free copy promotion from the package - when you buy The Ship now, you'll only get 1 copy of the game.
To reflect these changes, we've permanently reduced the price of the Complete Package from $19.99 to $9.99.
