This mod is a must have.
It incorporates it'self flawlessly with the released game, so much that I second guess myself when I think something is added by the mod, or I just missed it previous play-throughs.
I've only played with the mod for a few hours, but I'm really interested in the content that links the two games (partially just because I want to hear the voices of my old favourite characters); of which I've experianced only a tantalising morsel. I can't wait to get into the HK-50 and HK-47 content.
