this game is great, looks very good on the PS2, i never played before, it has some very nice jungles, you can control your team with the triangle button, and tell them to aid you in several ways like, heal the team, heal me, ammo needed, also you can tell them to move to a point, open fire, suppress fire, etc.

You can aim with the L1 button and that looks awsome, the only problem is that there's a lot of  Vege stuff and its difficult to spot the enemies, the first mission is in colombia, n' you have to secure a village, destroy all the enemies, and the boats for the drug's transportation qith the satchel, you can select the different weapons by pressing either sideway on the directional buttons, pressing up directional will show the binoculars, and by pressing down you can see the night vision googles, this game really looks awsome, and in medium difficulty is really hard.

Until now i know that you can use some placed machine guns, and by pressing action, mainly on the wooden surveillance towers, you can change/replenish ammo/weapon., and that will be handy.

By pressing the R2 button you can see the grenades menu, and pressing X you can throw your selected grenade, which can be Frag, Smoke, etc. By pressing circle you can change into three stances, standing, crouching, and if you hold it, you will lie on the floor and walk  with your elbows, the game looks and sounds fantastic, the second mission you will have to take out a radio plant without raising any alarm, and kill all the enemies who can oppose future resistance.

To summarize, is pretty cool, and real hard, buy it, won't regret it, that's all i can say by now.
