Hey guys, I noticed the Museum in MW2 at the end of the Campaign, and I just was wondering if there is even any reward or anything for killing every enemy inside. I heard a rumour that if you kill them all you can get outside, but I've tried this and nothing happened. Can anyone tell me if there is even any objective at all in the Museum? And sorry if this has been posted before, I searched for it 3 times and nothing came up.
Thanks,
Jackyboy
