Me and three others on the Infected team. Four on the Survivors team. Start on the first map on Normal difficulty; after all, it's mine and a few other's first time on the game (but not the series).
I get selected to be a Charger. So I place myself in a corridor near spawn, then see that I can be in a small room behind a door. So I place myself there.
As my Boomer and Spitter team-mates softened up the Survivors with vomit and acid, then finishing with the Boomer exploding on the Survivors, I waited still.
The last of the four limped past, then decided to open the door. Bad move.
CHARGE! WHAM! Picked up the survivor and started smooshing him against the floor. Other survivors break rank in a mad rush and flee. That's one down.
I chase after them, and once again I pick on the straggler. Hunting as any good pack animal would, I barrelled into one of them, right in an area where they need to go on a narrow ledge to the next point, knocking myself and one off right into instant-death, and a second into the Incapacitated state from clinging on for their life.
I spawned again not much later as a smoker, found the one on highest health, and dragged them off the roof into the abyss. Three deaths in about three minutes.
