The drillers were cool. But how did you make walls explode as you passed them?
Come to think of it, how do you make smoke move in a certain direction? When I put it in it always goes down (especially when I want it to drift up from lava). It's not even realistic (smoke should gather near the ceiling).
Well, about exploding walls I did not made any dynamic exploding walls on the level (the only exploding wall should be the hostage door) If you mean something different, please enlighten me up (where and when you see the exploding walls on this level?)
And about smoke it has to do with object direction. If you insert a smoke object on DLE-XP, you can move the arrow (green arrow when you select it on object mode) of the object and you can also rotate and turn it. Just be sure the object arrow's head is looking at the direction where you would like the smoke to be spewed off.
