I swallowed the very large but very necessary pills of the first playtest's feedback and made some pretty substantial changes.
- Replaced fence w/ building offering high and low ground for both teams
- Reworked left flank room on first point
- Added geometry to block oppressive sniper sightlines
- Moved second point up and forward a little
- Blocked off the long hallway into second w/ truck. Both teams can now access high ground inside computer room
- Added ladder into window as a means for BLU to get to B faster
- Other changes I'm sure I'll remember later
I saw a few issues with demo spam and I forgot to add patches under my health and ammo. Those should all be fixed now.
