Beautiful Locales, High Octane Action, Drugs, A Decent Story and dumb AI make this game "worth playing".
The guns in this game are not many but are just enough to keep the variety. But there are just four types of clothes - Normal, Armor, Suit and one unlockable Cheat suit . The clothes and the guns you use during your mission decide how much reputation you earn at the end of your mission.
On the first mission it has you saving a drug dealer from the mafia who becomes your inside man from whom you can buy information about the upcoming missions. As you progress the missions become a bit "less easy". Some missions require you to steer a boat while spraying your SMG's at other boats. There are lot of Med Kits to be picked up and so are Drugs. There is a "Flash RAM" to be picked up in each mission which you can later hack at the police station to unlock Upgrades and Drug Baron locations.
The game uses a arcade style minigame to emulate the hacking. It is initially easy and grows in difficulty as you progress.
But one of the most interesting thing in the game is the Drug dealing. You can pick up drugs during mission and sell them to drug dealers or drug barons. Selling drugs to barons is all together a different innovative minigame which keeps the game from being a bit too repetitive.
The story is good and keeps the game a bit interesting. Although a bit easy I would recommend this game to anyone who likes action and has a PSP. Definitely worth giving a shot.
