YMMV: Darkest of Days
- Game Breaker: Extended mags and fast reload upgrade works this way, especially for pistols. You can behave like you are wielding full-auto weapons, while everyone else is with muskets or bolt-action rifles.
- Holy Shit Quotient: Any mission that features the player as one man in a 100-man army, going against another army. Which is most of them.
- Nightmare Fuel: Wounded soldiers screaming for medics and trying to drag themselves away from the battle, citizens of Pompeii screaming as the volcano erupts or you burn them to death with the FMG.
- The concentration camp.
