In Modern Warfare 2, are there any achievements in the museum?
I've completed Modern Warfare 2 and gotten bored of online multiplayer play. (I have a lag problem)
Are there any achievements to be won in the museum level? I want to get them all.
No, there are no achievements for that level.
There is an easter egg where you can walk over to one of the museum desks that has a button. Pressing the button makes the characters come alive and try to kill you.
If you want to complete the achievements, you can find a complete list here. If you need help, you can also consult the achievement guide.
