On the obvious side of things; @Cage; Sure that's an anglehead flashlight, they were commonly used by the military.
I found a few more chunks of stuff in 0.99;

E1L2 from above, a few differences. Still retains some things we saw in the stuff Darkus found though is clearly a much later revision. The shot witht he "All work and no play" from earlier has a red "A" tagged like a camera (0,300) in it, this may mean nothing, otherwise the sprite may have changed tile since that part was made (Where was it in Lameduke?)

Another unused area in E1L2, seems like it may have connected to near where the Duke Burger is in the N64 version, presumably a blastable wall would allow access. Contails loads of Liztroops and some ammo. Speaking of the N64, the fire station reminds me of the grocery store in the N64 version of E1L1.

Pieces of E1L5, the round piece was likely for copy/pasting in the battlelord arena, the othe piece at the edge of the screen contains an octabrain and a door with shotgun ammo behind it.


This may be in the final... Can't remember nor do I have access right now. Made me chuckle though as the only thing I know SUYT to stand for is "Show us your t*ts" - levelord must have been feeling a little frustrated that day.
