It took a while for me to notice: Left 4 Dead 2 has Swiss strongboxes in many levels, but disappointingly they’re filled with medical items instead of laundered money:
The amateurs at Valve have never been invited to a Swiss home, I guess, where after the evening’s competitive yodeling one usually retreats to the chalet’s upper floor to peruse the contents of the wall-mounted strongboxes, making sure none of the clock parts or hidden Jewish gold was stolen while one was outside.
