Differences with Build and Doom Engine

Dunno why everyone is talking about Duke's bugginess, I recently replayed the classic 3 episodes and haven't encountered any problems.

It was mostly in custom maps but there would be crevices that your character shouldn't be able to enter and you would get crushed if you walked up to them to right way.

Palettes can even be assigned to sprites, though this wasn't visibly used. You can use higher values to make simple recolours of monsters, such as pig tanks with blue armour or the flying assault commander with orange skin. These were only used in-game for the mini-battlelord though, which was literally a standard battlelord but with palette 21.

(You can also use palette 21 to make Mini-cycloids and mini-overlords, but they only have 1 health)

IIRC, you needed to use palette swapping in order to distinguish the Assault Trooper (Green) or Assault Captain (red) enemies. Otherwise it would display a light blue Assault Trooper by default. Or was it they had a different sprite set for each? Been ages since I messed with build.
