Hi there.
I've been working on a major rework of level 2 mainly for the past week or so. From my current knowledge of the Shadow build engine, level2 is so poorly built it's laughable. That said, I wouldn't make too many structural changes. It is a weird map in a bad way with many incoherent puzzles. It's like fixing it to make it reasonably playable level.
The atmosphere/design of level2 will basically look like this.
The office for customer service has a different, homey feel.
And as an unused character in the original SW, she appears at level 2.
Again, I don't have much to say.
See you soon.
