Nice to see things starting to happen with Rise of Flight! In a recent press release (Russian) by publisher ND Games, the collector's edition of the game was announced (pictured above). Looks like it includes a few extra goodies such as a colored manual, wings lapel, a "club activation card", and access to the Russian-built Nieuport 17 (which we previously heard was being offered to Russians free of charge).
Closed beta testing has started, and it looks like Neoqb has the forums and everything setup. According to the press release, the game will be released in May. The publisher had originally said it would be released in April (this month), and actually it still says this on the game's profile (Russian). I'm assuming the more recent press release supercedes that!
So for the time being, hopefully the bugs can be fixed during the closed beta, and hopefully enough we'll keep getting more information closer to the game's release. Excitement is building as more and more people discover Rise of Flight!
