Versus Books' "Perfect Guide" from the year 2000 (cue Conan O'Brien)
Packed full of detailed analysis of every mission in the game, weapons, enemies, maps, and strats, as well as a breakdown of the multi-player mode.
This copy has no poster, and the upper right corner of the front cover has a small crease line. The bottom right corner of the front several pages also has a tiny (< 1/4 inch area affected) bit of curl. Other than that it is in excellent shape!
