I decided to write a clarification for what's happening at PC Gamer Weekender, as we know it right now.
Bear in mind this is subject to change and PC Gamer are handling everything so it's really their place to provide this information.
Our demo (with 40 mins of gameplay) will be done twice at 1pm local time - once on Sunday and once on Saturday. At least one of these will be recorded and shared in full, after the event. Probably not too long after, but maybe a week or two.
In addition to this, there will be a livestream at the event, in sort of a couch format. We're going to have a slot there (probably on Sunday but again, subject to change) though it'll be a shorter than the stage demo (the slot is 20 minutes, as far as I know).
I hope that clears everything up.
