Season 5 is now live for Star Trek Online, but the actual conversion to free-to-play is still a little further ahead. That means there's a grace period during which players can be given a few extra little perks for sticking with the game. Said perks have been outlined in the most recent Path to F2P blog entry. Until January 2nd, the classic Constitution-class ship and the Klingon Qorgh Refit are free to players who log in and claim them from the C-Store.
Subscription deals are also being offered through December 19th for players who subscribe for longer than one month. Picking up a three-month subscription will come out to around $36, and a six-month subscription will run about $66, both cheaper than the regular pricing. You can also pick up a lifetime subscription as well, if you're willing to drop $200 up front. While some players will doubtlessly be taking advantage of the shift to stop subscribing and keep playing, there's certainly no shortage of deals being offered to keep subscriptions after the switch.
