PTU is all waves. Even the worms have spawned in...
(They really struggle with ringfencing areas... Worms have been emerging through concrete for most of the PTU run)
EDIT:
Berks mentioned the solid 30fps server tick. [You can see it top right in this vid].
Then PES fell apart instead...
(He ended up backspacing)
(This is literally a fresh patch. How the hell is PES falling over already?)

(EDIT2: As an aside, he's not crazy impressed by the new
'mid-worms mobbing you' scenario being the main challenge. Guess they're struggling to get the big boi balanced).
