A little hard even on normal, but if you love tactical games, this is a must! There's also co-op campaign onlne!
The campaign is very very nice. There's a nice training mission which really shows you the game and what to do, the main letdown for tom clancy's rainbow 6 2. The actual campaign is incredible, you get 3 other al ghost that help you, they don't really kill that many soldiers compared to you, but they are nice scouts =) On top of that sometimes you can command recons, tanks, and even helicopters!
Multiplayer and local play can both do co-op campaign, deathmatch, team deathmatch, etc etc. Deathmatch and team deathmatch aren't really that good, the reason being, it's a tactical game, not halo 3 or cod4. However co-op campaign really adds on to the game. It's nice and exciting when you have 5 people + fighting alongside you. Respawn points can be enbaled, however too many people run and get themselves killed, knowing they can respawn. You can have guest online so you could have 4 people on your tv and then 4 people on another Tv, in another country. The system link is pretty nice, espically if you have a huge party. Same features and multiplayer.
Pros: A must have for people, even those that have never tried tactical shooters. Lots of features, making this game with a lot of replay value. The training mission shows people what to do for first timers. Nice and cheap nowadays, and it still is super good.
Cons: Can be a little hard sometimes there's only normal and hard for campaign, no easy. Deathmatch isn't really that good, it's 3rd person not 1st.
Conclusion? Get it, you can find it super cheap, espically amazon, I'd say about $15 max used on amazon, including shipping. They have it for xbox and ps2, but from what I've heard, not that good.
