Lego Land v1.0
A smallish map that looks bigger because of the confusing choice of textures. (Doors don't always look like doors, especially if you're under the influence of the relatively common IR powerup.) Nice flow, though... comes with a film. The minibobs and pfhor can be pretty annoying until you kill 'em all...
