two sides to this game
On the good side we have the multiplayer- it's a good tactical shooter with plenty of game modes to choose from, it'll take a while for this to get boring. Didn't get to see a huge amount due to psn going down, but what there is was spot on.
On the bad side we have the single player - tedious and definitely not tactical! move from A to B killing off the doom like wave of enemies. Watch as your squad yet again gets wounded, or gets in your way if you don't command them where to go. Multiple headshots to kill enemies and repetitive missions make this a chore to complete. Socom has always been an online experience so i would stick to that, it's worth it.
** UPDATE: Having now played this game extensivley online, i would say stick to COD! I hate to say it but this is no tactical shooter! spawn camping and spawn sniping, no team work and the usual idiots make this a poor 3rd person shooter.
