«Cave - ins» just sounds like a really
fancy way of saying «we're cutting off areas in which you can fight» — the restricted - movement
catch that's made Battle Royale games so exciting and
fast - paced.
Also I remember the old Sonic games letting you go so
fast the camera couldn't
catch up with you, but, uh, now they probably have more advanced and
fancy thingies so it can keep up with you?
