The 13th difficulty level. 9 levels above Expert. Harder than Ludicrous

Thanatotic is a difficulty level made based on the vision of the author "Iizvullok" as the next step above Ludicrous (includes a Realism version as well)

Things that have been changed: - special infected limit is 8 - survivor base speed locked near critical pace (custom speed control) - permanent health forced to 1; temporary health is tightly limited - first aid kits are removed from the map - pills/adrenaline provide almost no real recovery - higher infected stats than Ludicrous (health, damage, speed, spawn pressure) - always black and white - adrenaline speed boost is limited - other small balance changes

Thanatotic is the peak of the main progression line beyond Insurmountable → Inconceivable → Ludicrous. It is built around permanent fragility and constant special pressure. Expect short attempts.
