They make sure they are fully loaded as they prepare for the entire floor full of classrooms.
It won't be easy with how strong the mutants have become. But it will be worth it for the points they will gain in the end.
They slowly and carefully enter each of the 25 classrooms on the floor. Each room has a mob of regular zombies and a minimum of one mutant as the commander of the room.
The squad begins to systematically defeat each room.
Usually by opening up with a barrage of bullets from doom pistol, heavy minigun, and heavy assault rifle.
Gobinia usually finishes the mutant with one of her explosives for good measure. Or at the very least the explosive deals some lasting damage that makes the mutant easy to finish off.
But as the rooms are cleared and Garrett sells the desks and chairs and other items that are sellable. The points climb up fast as they get through more and more of the dungeon.
