Tom Clancy's Ghost Recon Advanced Warfighter 2 review at GameAlmighty.

"Of all the platforms on the market today, the PSP is the most ill-suited for first-person shooters, so its not hard to expect Ubisoft's translation of Ghost Recon: Advanced Warfighter 2 on to the handheld to be a difficult one. But surprisingly it is one of the most approachable and well controlled FPSs on the system. In porting the system over, it appears Ubisoft wisely choose to go for a spiritual cousin to GRAW2, rather then try to shoehorn every feature of the home console versions into the handheld. This may frustrate purists and hardcore fans of the series who are looking for some of its more distinct features such as the cover system and squad control, but lets be honest with ourselves, the Advanced Warfighter games themselves are a big departure from the original Ghost Recon on the PC."
