This looks ace.
Are the first 2 games in the series worth a play through? I'm thinking about the storyline?
You don't need to necessarily play the other two to understand the storyline but this game is a sequel to Shadow of Chernobyl. Furthermore I would recommend playing Shadow of Chernobyl (Complete mod) being my favourite of the series. Imo Clear skys was the weakest of the series I haven't even played through that again.
