A few weeks ago I designed what I consider a new, improved training mode for TF2 on Facepunch.
The training mode I came up with:
For the 72 hour contest I'm working on a script for the training mode mode. So far I've done the intro, the Scout, Soldier, Pyro, Demo and Heavy. I didn't do every bit a dialog (for example I didn't talk about the melee weapons for every class).
I'm hoping to finish some more of the training and maybe do some polishing of the document before the end of the contest.
Included is a Google Docs link since I couldn't upload a document.
