Being able to record is an amazing feature that has multiple purposes regarding both casual play and competitive.
Is there any chance of seeing this in future versions of the game, i.e. /demo 123?
Yeah actually, it’s called Fraps. Download it/buy it, and record! There you go.
I think he means more of a TF2 style option where your given the choice to save your last life instead of having to sort trough hours of replay data to find that awesome kill streak from that one match that one time.
Personally I use fraps but an in game record implementation would be freaking radical!
There is a console command to record movies but it makes the game super laggy and unplayable.
