I have said this in the quick comment but still saying it again. name could have been thought out a lil better for there aren't many cities in the jungle. and yes agreed not much difference in play from the other two
Yes I noticed that there isnt much difference. That would be nice if there was more characters, with different abilities. Also It would be nice if there was achievements.
There is virtually no difference. I found it to be far easier and faster than the other 2 though. I didn't feel satisfied with the game.
As far as strategies go, the spy is key. It has been modified to have a melee range attack instead of a time bomb. Go in, shank who you can, and save as many civilians/VIPs as possible. Then bring in something heavy (I prefer the Heli-R or Tesla) and clean up the rest of the baddies.
There's one thing you should always remember in CS3: JS is always I mean always promote the spy so she can't easily die when she is hit by a bazooka guy.
