Second Wave
After the wave of ferals and sprinters came the second wave where the regular deadheads were at their highest.
Almost all of them were marching forward as their rotting bodies were literally side-by-side, worse than riding a bus while the person next to you was jerking off. It was like seeing deranged shoppers at an opening of a Black Friday Sale, pushing and squeezing against each other just so they could get to their targets first.
From a select few, their bodies had almost congealed to each other probably due to being in a confined space for far too long while some got their bodies chewed up by the ones they chewed up as well.
This was the only time where I've seen beings consume more than half of their body weight and lose more than half their body weight as well.
