Also, while stealth played a significant role in the console version, it won't help you much here; you can creep around with your knees bent all you want, but the baddies will usually catch you if you try to get in close for a kill. Sneaking wasn't all that was cut from the PSP version, either; no less than six of the original 14 missions were removed from the game, replaced by 16 mini-challenges that have you doing things like racing through a certain stage in a jetpack, or seeing how many enemies you can kill within a set time limit. These are fun, sure, but they're a poor replacement for driving, boating or outwitting a tank - especially when you consider that this expurgated version can be played through in an afternoon.
