Favorite Small Map ?

[Spowmtom]

Sometimes, you just want to play Doom for 5 minutes while waiting for whatever and you simply don't have the time or patience to finish a medium or large level.

An example of a great small map would simply be E1M1 and MAP01 from Doom and Doom 2 respectively.

 

What are your favorite small maps ?

Most of Scythe's first episode, Doom's E1 and E3, Decimal Error from SF, and that's pretty much all that comes to mind right now.
