At first I didn't think the TF2 integration was compelling, but its actually great for demos and experiments. Launch a map through the console and set sv_cheats 1
1) Set no_clip
(toggles) and fly like superman. Combine with vr_moveaim_mode
to test control schemes (set 1-7).
2) Try some custom maps. tc_meridian_b2 was a cool medieval castle, ctf_spacebase_b1a has an interesting outer space theme, ctf_premuda_b1b has rain, etc. List your favorites in this thread! http://www.tf2maps.net/
3) Check out third person mode by setting thirdperson or other variations at http://wiki.teamfortress.com/wiki/List_ ... e_commands
. Combine this with vr_moveaim_mode 1
to see your avatar face on.
4) Try medieval mode tf_medieval
TF2 should be great for super fast prototyping.
