Actual wheelchair usable in game by survivors or killer
Wheelchair could spawn by burning offering or some number of them by default.. Could be used by downed-slugged survivors to reach generators or open gate. Wheelchairs could give some speed-boost, also by driving in them you could drop pallets, but no window vaulting. Killers could push them over (one hit) and hook slugged survivor as usual, also do some kind of damage to the wheels or make survivor stuck inside chair. Only other survivor could rescue stuck survivor or killer come later and hook them last. Damaged wheelchair could be pushed by the killer to whatever place he wants to bait out other survivors. Survivor alone can only crawl into wheelchair, wheelchair auras are revealed to downed survivors. Survivor bleeding timer stops when he's sitting in one. Survivor can heal himself only in undamaged chair, in damaged chair survivor is stuck till gets rescued or killer comes and hooks him.
