OK! FIRST got to ip chicken or type your "what's my ip" in google. Or tell the guy you wanna play with to get his ip from what I just said. Then remeber the guy or gal's ip, next open uber soldier 2 and go to multiplayer. There should be a place at the bottom of screen that allows you to type numbers. Type the IP of ur friend or whoever's ip you wanted to join(MAKE SURE THAT THE PERSON YOU WANNA JOIN MADE A SERVER!) Then TADAAA! You should be joning the game then have fun!
