yes, a very oldie but goodie....
i have the combo that i used a month or 2 ago where u could teleport/switch teams...
its basically an exploit with cams where ur stuck in cams of the map....so that's why you teleport around...except on maps such as inferno cause there is only 1 cam so you can move around as you please.....
the way i got go move around was always drop something, no matter what, whether it be a pistol, rifle or whatever and it should let u move....
still a fun one too :D
