I was playing special ops and we were holed up in a diner holding wave after wave of enemies, and we were on the last wave, with just a helicopter left, and we could NOT find the damn thing!
Finally I got so frustrated I just ran outside, the predator drone got a lock on me, it fired, an explosion and....MISSION ACCOMPLISHED
Looking at the post game stats, it said me and my friend each killed 1 helicopter for a grand total of 2/3 helicopters, which CONFIRMED that the ENEMY predator drone shot down the last freaking helicopter in that special ops mission on veteran, thus winning the game for us.
I couldn't make this shit up if I tried, we laughed for HOURS.
