Unreal Giant Maps

Unreal Tournament 2004 has lots of excellent deathmatch levels that are gobs of fun to play (*cough* DM-Rankin), but in terms of sheer ingenuity, I haven't seen anything that can beat the line of 'Giant Map' levels, which place inch-high players in a bathroom (above), basement, or kitchen:

Naturally, these levels aren't too balanced for competitive multiplayer, since people on the the wide-open floor can be easily sniped by players on inaccessible higher ledges, but it is wicked odd to see someone unleash an ion cannon inside a giant house ^_^

PS: Wasn't there a movie with tiny toys with weapons inside a house? Can't...remember...name...
