It's a big project, so it's important to test everything thoroughly and run several tests. "The Lost Citadel" had a lot of bugs in the first release because I didn't test enough. I will not repeat this mistake.
I have fixed all problems found during beta 2. Beta 3 shall include all subtitles and briefing videos. The problem is that I'm still missing some voices. This means we can't complete the game subtitles and produce the briefing videos. In the worst case, I'll have to do a new audition for this stuff, but currently I don't feel like it.
