Splinter Cell co-op ?

i've been doing some research and i found Splinter Cell: Chaos Theory and Double Agent have offline co-op modes, correct?
how is the co-op gameplay? id like to play this with a friend and wondering if its worth the purchase or not. thanks

Hello, I have both Splinter Cell games, they're very good. It's fun to play the offline multiplayer mode. (Sorry if you don't understand me, I'm Argentinian) It's a split-screen mode, You play with someone a story mode, with cooperative actions like open a door with two key cards, I recommend it to you.agux987
