I first played this game on a demo I had for the PC and after playing it a few times I decided to pick up a copy for my Gamecube. This turned out to be a great decision as it's a fantastic game.
The best aspect of the game is the fact that you can carry out your mission however you want to. For example in one of the early levels you have to kill two generals who are meeting in a public park. They have plenty of security and it's up to you how to carry out the mission; will you scale a church building and snipe them from above, will you go into the sewers and place bombs under their limos or will you just go in all guns blazing?
Each mission has a number of different ways in which you can complete it.
There is good variety in the types of missions as well, they take place in country villas, luxury apartments, old villages in a desert, in icy wastelands and plenty of other locations. There are a massive amount of weapons in the game, from your standard pistol, AK47, sniper rifle to less conventional weapons such as a golf club.
The game encourages stealth however you can just go in all guns blazing but you'll probably get more enjoyment from getting a stealthy rating and perhaps not killing anyone apart from the target rather than mmurdering everyone in the entire level.
I thoroughly enjoyed this game and would 100% recommend it to anyone who enjoys shooting or stealth games!
