(adsbygoogle = window.adsbygoogle || []).push({}); this is a way to let the game complete its own levels.
HOW?
*start the game without signing in.(sign in when the match started) to bypass the patch.
*Start survival mode.outpost. complete 2 levels and get a sentrigun. meet me at the wallrub at the tunnel.
*breach the tunnel and go under the map, walk around to the tanker and place the sentri, so it faces the back of the truck.
*go back in the map and get a sentri-bomber.
*place this in the tanker,facing the door, and stand against the back of it. (there is exactly enough space for this)
*$ U can leave the ps3 on and let the sentri's do the work $*

Cool glitches commin up....

awesome find, as always keep it up

It's a good job

when i was signed out for only2 seconds, it didn't count towards the leader boards. i might work for the glitch but it won't count for rank

thanks. also confirming that the 3 gun glitch works as well

it does for me..
try: SIGNING IN AFTER U STARTED GAME, then restart the mission.
the glitches are still possible aslong u dont go to the lobby inbetween 2games.

thanks it works on ps3,
but i cant still get under the map
get in to truck and take sentry gun. very easy.i made 25 round in first time and its crazy..

try Being on the XMB Signed Out, Go on spec ops, And start the match, sign in when it starts, Should work. Thank me If it works, and it will work cuz i'm doing it now

i think its patched now? can anyone do it? I just die if i get in even the slightest
