Two votes available as I begin writing this (Sorry Dim and Lindblum bros), and they're not mutually exclusive. Cherie decides she'll check out the rest of this office building for supplies, replace her hunting rifle with a shotgun and as many shells as she can carry, and take a nap before going back to the facility. Cherie scarfs down 3 cans of food, loads that single extra hunting rifle bullet in to her rifle, and picks up 3 boxes of shotgun shells and steps outside.
Cherie can hear screams of terror from the east, but heads to the north for now. With no decent bed to sleep on, the only way she'll be able to heal is with medkits.
Cherie, loaded up with a shotgun (5 shells in it), 40 reserve shells, and an extra medkit after using one to bring herself to full health. Before barricading herself and preparing to sleep, she decides she better check out the rest of the offices and find out if that screaming was in the building or not.
Near the end of her search, Cherie finds 4 more cans of food, another medkit, and... 5 grenades! She quickly replaces one box of shotgun shells with the grenades, which sound like just what the multi-headed dicks called for. As she does this, motorcycles roar in from the east. MORE raiders? This is getting out of hand!
As she steps outside the room to investigate the final part of the building, Cherie sees a zombie Prince wandering down the hall toward her. Did it follow her up from the stairs, or did it wander in from outside? Whatever the case, Cherie has to take care of it. Cherie decides on using her shotgun while she's upstairs and more shells are plentiful. Best to hang on to her grenades when down below.
Cherie quickly runs past the zombie back in to the room she just came from, and fires a blast at it. The shotgun is less effective at two squares away than in melee, but Cherie has seen what a zombie prince can do and would rather avoid it.
Uh oh. While backpedaling and pumping shot after shot in to the prince, a second begins to enter the room. Cherie briefly considers using a grenade, but in close quarters like this, and with the first prince nearly dead, she decides against it. She finishes the damaged prince off, and begins kiting the full health one back down the hallway.
Fuck! FUCK! FUCKFUCKFUCK. Total ammo remaining: 16 shells. Cherie runs for the upper room, which has more space to kite zombies, and finishes the most damaged prince in short order.
FUUUUUUUUUUUUUUUUUUUUUUUCK. Total ammo remaining: 11 shells. FUCK YOU ZOMBIES, AAAAAAAAAAAAAAAA. She takes down the prince and shambler
FUUUUUUUUUUCK YOOOOOOOOOOOOOOOOOOOU. Total ammo remaining: 4 shells. Cherie decides it's time to lure the zombie to the side of the room, then bolt past it and make a run for more ammo. The run rises as Cherie waits, and she gains a point of necrology.
FUCK FUCK FUCKIN' ZOMBIE FUCKIN' FUCKS.
ASS. ASSSSSSSSSSSSSSSSSSSSSSSSS. Cherie gets winded while running down the hall, and is slowed to speed 0.66, just barely faster than the zombies' 0.50. She pulls a grenade out and lobs it one square to her left and dives for the doorway.
The grenade goes off and damages at least the front zombie. She scrambles over the chair and to the shotgun shells she left when grabbing the grenade just as the front shambler lurches for the doorway. She puts two shells in to it before it drops. She reloads her shotgun and moves in a slightly better firing position for the doorway.
That's great, IF ONLY THEY WEREN'T ON THE OTHER SIDE OF THE DISTRICT! Cherie hucks a grenade at the shambler and starts firing. 4 shots and she brings the zombie down. She cautiously advances until she can see the prince, and lobs a grenade directly on to it when it enters the doorway.
Total ammo remaining: 8 shells, 2 grenades. Cherie begins firing and backing up, in 4 shots she gets the zombie prince down to 2HP, and finishes it with a smack of her shotgun. She steps back up and finds a dark shambler entering the room. She uses a precious grenade which damages it for 60HP, and starts firing her few remaining shells. The final shell in the shotgun kills the dark shambler, just as another moves up to take its place.
Total ammo remaining: 0 shells, 1 grenade. Cherie's only hope is to run past the zombie, hope the hallway is clear, and make a dash for more shotgun shells. She'll soon be sleepy which will slow her down and her advantage of speed will be lessened.
Success! The hallway was clear, and she was barely able to avoid the shambler! She picks up the stamina pills in the hall which may be useful in a pinch in desperate times like these, and runs to the room with the most shells in it. Total ammo remaining: 19 shells, 1 grenade. She stands in the room, waiting for the shambler to appear.
That's... Not the shambler. At least Cherie now knows where the undead are coming from. CHANGE OF PLAN, if she can take out this prince and the shambler, she will barricade the iron door as much as possible in the hopes she can get some time to breathe. Cherie times her throw so it lands right in the hallway as the prince enters it.
Another shambler coming up from the basement. FUCK ZOMBIES. FUCK ALL ZOMBIES. Cherie destroys the prince and shambler, and picks up the remaining box of shells in the room. Total ammo remaining: 19 shells. She also grabs some planks of wood and begins moving toward the iron door.
One fully barricaded iron door. Unfortunately Cherie knows there's more shotgun ammo in that room, but she wasn't willing to take the risk picking it up when she had a chance to barricade the door. Whew.
ALRIGHT CODEX, time to guide Cherie. At this point she's still reasonably well fed and has 3 cans of food on hand, and there may be more shotgun shells in the other explored rooms to her left, and MOST LIKELY more shells in the giant office building to the right. Cherie has just about hit her sleep tipping point which will slow her down, so sleeping would be a good idea. But where should she do it? Should she take more wood and barricade herself in one of the offices of this building? One of the other buildings in this area? Take the long sleepy walk back to her semi-safehouse in the shopping district to the north of here? There's no more food stashed in there, so the merits of that would be questionable, but it DID seem a bit safer.
PS Lindblum, yet another level where leadership wasn't an option. I kept my eyes peeled specifically for you and didn't have the choice.
Visual approximation of Cherie at this point:
