/recorddemo + /gamespeed 30 = TAS in the Cube 2 engine!!
Probably not the right place to put this but this is something I discovered while playing a bot match. Speaking of which, I should mention that bots in this game learn what paths you take, and use that programming to use your own strategy against you; every bot in Sauerbraten is a doppelganger, effectively.
This could set the stage for some really interesting speed/entertainment tradeoffs, and I found a neat way to pick up speed: if you jump off a slope going down, moving toward the corner, it gives you an additional %15 speed boost, whereas jumping while moving forward boosts you about %30, so that means jumping off a slope toward the corner of it would be about %45 speedboost.
Hey, we're taking DOOM TASes now, why not Cube 2?
