Bummer, thought I was getting it when I bought it. Oh well. Any chance they will release this mission separately in the future? Also has anyone played it and is it any good?
Yeah, it'll definitely be released separately down the line: it has store subs in the Steam registry.
Is this game related to the others or is it a reboot? Is it worth playing through the 3 other games first?
A reboot. Some may recommend that you ignore Thi4f entirely but I think playing it first and then moving on to the The Dark Project, The Metal Age and (to a lesser extent) Deadly Shadows would afford you a greater sense of why most are disappointed. Having said that, though, the game's hardly worth full price, but I can almost guarantee you that the PC version will be half off somewhere within the next 4-6 weeks.
