Forum:Co-Op Question (Xbox)

Hey this is probably a stupid question but is there any kind of like "search" feature or something to find people to play Co-Op with? Very few people on my friends list have the game and I haven't been able to play any co-op at all and I really would like to as I hear that's the only way to get the best gear? Thanks! Otherwise if anyone wants to add me to their friends list so we can do some co-op my gamer tag is "Inphectid". Thanks!
