I'm not going to create an elaborate User page here (for the moment anyway), but I will direct you to my Official Team Fortress 2 Wiki User page if you are curious. Note: The linked page reveals very little, so don't get your hopes up ;).
NOTES
- Add Portal Gun image (appears to be concept art) from Portal: The Final Hours (Page 7, Chapter 5) to ASHPG gallery.
- Add set of Chell concept art from P:TFH to Chell gallery (Page 6, Chapter 6).
- Add trivia item about "diorama" content (unused) from Page Page 7, Chapter 7.
- Pages 8 and 9, Chapter 8; Add "underground track" concept art if it has not already been added.
- Page 5, Chapter 9; Add Atlas/P-Body concept art if it has not already been updated.
- Page 3, Chapter 10; Add trivia entry about "mean GLaDOS" and subsequent passive-agressive reworking?
- More Rattman art at the end. Does it exist on ze Wiki yet? If not, add it!
