1. Get wanted killstreak(has to be one that your call in and get an overlay ex. airstrike)
2. Call it in and quickly switch to your weapon ( just before your person opens the case)
3. If you see your gun behind the overlay congrats, you can use the killstreak again.
CREDITS: w00tare and his friend found this glitch
Heres a video showing the glitch: NOT MY VIDEO JUST AN EXAMPLE
Do I care? No, do I play mw3? No, I don't give a shit if your getting owned by glitchers they'll get banned and this will be patched. Your complaining about a video game where the perpose is to have fun. If this is how some pople have fun more power to them. You whining on my thread won't change a single thing.
Nope, you are the idiot... READ THE FUCKING WEBSITE NAME... This is the kind of thread which is supposed to be written. Like it or not, just dont write that bullshit here. BTW you cant get banned cuz of game glitches.
