We'll try to keep updates regular now. :)
In this video you can see as you progress through singleplayer you will collect your squad, there are limited controls to your squad atm. You can order them to move to certain point, follow you in a formation, or hold position for cover, as seen in video.
In multiplayer, you can attach yourself to your friend, and follow him in formation while you are focused on shooting zombies, quite usefull stuff sometimes!
