A new, revamped and fully voice-acted version of Blue Planet was released today.
I'm currently playing it, and it's really awesome ! Professional quality voice-acting and cutscenes (using the game's engine), great scenario so far... besides, the new ships are really well designed and coherent with the Freespace universe, and the skyboxes just look gorgeous.
On the minus side, this campaign is pretty difficult, particularly the mission Forced Entry : fortunately, there is an online walkthrough with useful strategies for this mission. Once you know what to do, it is great, but you'll have to fail a few times before succeeding since this mission requires a lot of anticipation.
In other words : if you haven't played this campaign yet, go download it now, it's an order pilot !
