🕐 12:00am "North Plaza Intro" call. Make your way to where David is located, in one of the empty rooms, and talk to him to get him to join. There is a bunch of food around, so stock up if you need to.
You don't have to do this next part if you aren't worried about getting 10 Psychopaths.
Now you have to lend David a shoulder, so do so and make your way as best as you can to the "Huntin' Shack" (N127). Clear out the zombies in front of here and set a waypoint for David to hang out at. Enter the Huntin' Shack and you'll meet Cletus. Once again, easy to kill with the Mega-Buster, but doable with any gun or the Chainsaws — just look for when he reloads or takes a drink to do the most damage. Make sure you grab a photo of him at some point too.
Continue here regardless. You can take David back to the Security Room either through Wonderland via the shortcut, or across Leisure Park. There's a good chance that if you enter Leisure Park the Convicts will be back — if you choose the park and they are back, look for them immediately; if you see them close by, kill them; if not, you're probably safe to just make your way to Paradise Plaza. Just keep David on your shoulder and you'll be able to run through zombies no problem.
When you return safely to the security room with David (don't forget to snap his photo!) you can enter the Security Room office now to finish "A Temporary Agreement" and initiate case 2-1.
🕐 1:15 You are now free to do whatever you want until 6:00am. First off, I suggest that you save if you haven't done so recently (or maybe at all) — if you've made it to here you are safe (for now). While you're already in the security room, grab some photos of anyone you may have missed, then head back out to at least the Warehouse — but just stay away from the Security Room until 6am. If you are in the Security Room at that time you will NOT get the next Otis call and will have no chance at Transmissionary.
This is a great time to head to the Maintenance Tunnels to get the "Maintenance Tunnels Intro" call. I'm going to mark this one #0 because it can be gotten at various different times, but do not wait too long, because there is some point in the game where you can enter the tunnels and no longer get this call. No joke — you can miss this call by simply not going into the tunnels soon enough. So if you don't have anything in mind to do but wait around, head to the tunnels.
"Maintenance Tunnels Intro" call (read the paragraph above if you searched to find this call).
🕐 6:00 Do NOT be in the Security Office or on the Roof at this time, and you will get a call from Otis to come talk to Jessica. After which you can head back there to proceed with the cases.
🕐 6:10 Go back in the Warehouse and you'll get a call that the gate between Entrance Plaza and Paradise Plaza is now open.
🕐 6:15 Go into the Entrance Plaza to engage in a scene with Carlito and Brad.
You now have to fight sniper Carlito — blast him with the Mega-Buster, force your way up close to him and chainsaw him, or grab some hockey sticks from the second floor sports store and go to town on him. Not a very difficult fight, just gets annoying when he shoots you and knocks you down.
After this fight you'll end up back in the Security Office. Now, if you recall when I mentioned that picture of Jessica for Kent, now is your chance — stand a little back from her and get all of her "Erotica" features in the photo, and you should get over 700pp easily.
Now leave and make your way to Wonderland Plaza via the shortcut. From here head up into the North Plaza.
🕐 7:00 "The Lovers" call. (Cannot be in Wonderland Plaza to get this.) Don't turn back for them yet — we are going to head into "Seon's Food and Stuff" (L3) first to progress the main cases.
"Supermarket Intro" call when you enter the store.
Head back to the pharmacy, and when you get close, Steven will appear. Make sure you get his photo and watch for his shotgun attacks. Any ranged weapon will take him down moderately well, but you can also sneak up behind him and chainsaw him pretty easily — not too tough if you just stay out of his way.
Now you'll have the pharmacy key — make sure you go back and get the First Aid Kit out of the pharmacy.
Time now to head back to Wonderland to get the Lovers. On the way, if you don't already have a Queen, be sure to find one here. In front of the Space Ride is normally a ton of zombies that you can almost always find a bee in — just hold on to it, because you're going to be glad you have it in the near future.
🕐 7:45 The Lovers are in "Run Like the Wind" (W201) on the second floor. Talk to both Tonya and Ross — do NOT give Ross a gun under any circumstances (he asks for one, but don't do it). Keep talking to them until they both agree to come with you. You'll have to carry Ross, but as long as you're carrying him, Tonya will stay close by — she is actually a pretty good follower. When you leave Run Like The Wind head to the right and down the stairs by the Food Court, because there are fewer zombies there than trying to go in front of the Space Ride.
🕐 8:00 "Hatchet Man" call.
Get the Lovers over to Paradise Plaza via the bathroom and all the way back to the security room. Don't forget to grab some photos and give Jessie the medicine for Brad while you're here. If you didn't get the photo when I said to do it before, get that nice Erotica shot of Jessie before giving her the medicine.
🕐 9:00 "The Coward" call. (This call may come while you're escorting Tonya and Ross back — answer it and get them back.)
When you get back to Paradise Plaza you'll find a girl screaming in front of "Child's Play." This is where you want to have your Queen, because she is swamped in zombies. Clear them out and then talk to her to get her to join. Her sister is just chilling inside the store she was in front of, watching Pamela die, so get up in there with Pamela and talk to them a bit to get them both to join. They are both whiny and annoying, but get them back into the Warehouse as quick as you can.
Clear out the Warehouse and the elevator, but don't go up it yet. Take their photos if you haven't yet, and then just wait until 11 in the Warehouse (not the roof!).
🕐 11:00 "Medicine is Working" call (do NOT be in the Security Office for the case or you won't get this call).
"Restaurant Man" call.
Now that you have both of those calls, get Pam and Heather back to the Security Room and go in the office to advance the main cases.
🕐 11:15 Head back into Paradise Plaza, and if you don't have food, go up to Columbian Roastmasters on the way and grab something, then go down to "Jill's Sandwiches" (P104) and talk to Ronald. He'll want some food — once you give him some he'll join and give you a nice photo opportunity. Break the barricade to exit Jill's Sandwiches and just hang around until noon when Kent shows up.
🕐 12:00 Kent should run up to you, or just go talk to him — he'll ask to see your photo. Select the one of Jessica that's worth over 700pp and show it to him. He'll then set one more date for you guys to meet up at noon tomorrow.
Now get Ronald back to safety in the security plaza.
🕐 12:30 "Above the Law" call. Make your way out to Leisure Park and kill the Criminals if you come across them — if not, don't go out of your way, just head over to North Plaza. Enter "Crislip's Home Saloon" (L2) to the right.
You'll have to fight Cliff here — he's kinda crazy, but just like all other bosses in this game there's really not much strategy aside from having the right weapons and killing him before he kills you.
Take a photo of him sometime if you need to, and after you defeat him you'll get the Empty Room Key. Leave the Saloon, and right outside is the empty room — open it to find some survivors. Close the doors behind you so zombies don't walk in while you're talking to the survivors. Get them to follow you, and note that they can all use weapons if you have any for them.
Now, back into Leisure Park, head towards the Food Court. Once again, if the Convicts pose a threat to you, take them out; if not, don't waste any time.
🕐 1:50 Move from the Food Court into Al Fresco to "McHandy's Hardware" on the left, across from the fitness place. Set a waypoint in the back for all your survivors to hang out at while you talk Gordon into joining. You'll have to hit him at least once with something before he'll even consider joining, so get that out of the way at the beginning and then just talk to him until he joins.
🕐 2:20 Now head back through the Food Court into Wonderland Plaza.
Now you have to kill Jo the Cop to get her survivors. Time is running low on "Another Source," but Jo will begin to kill off her survivors if you wait any longer to do this scoop, so be as quick as you can killing her and freeing all her survivors. Photograph Jo if you need to.
Note: if you really can't do it and don't feel like retrying, skip Jo for now and continue back to the security room with the survivors you have. You can let 3 survivors die and still get the 50 survivors achievement — Jo has 4 survivors with her.
🕐 3:00 Call to return to security room. (Do NOT be in the Security Room office to get this call.)
If you did defeat Jo, you have 8 people with you right now and you're probably getting real frustrated. You can get them all back, trust me, but it will be annoying. Bite your teeth together and press on — just don't save in the middle, because if you don't make it you're going to want to start from your last save, not the beginning of the game again.
If you get back to the roof and you can't get them all up by the air duct and you're about to lose the main case scoop, just go in and finish the case — the survivors will not die in that time, and you can go back out and get them after the next case begins. If you have made it here, save! You do NOT want to do that again, I know you don't.
🕐 3:50 Head back to Paradise Plaza again — the Raincoat cult will appear with Jennifer. Kill them off and get Jennifer out of the box. Go to the bathroom and take the shortcut over to Wonderland. Hold Jennifer's hand to make your trip easy. (Don't forget a photo!)
🕐 4:15 In Wonderland now you'll have to go to the back end where the bear is to get Nick and Sally. Leave your marker in the bathroom so Jennifer will stay put, and go for them. If you've never saved them before, you'll notice there is a hefty swarm around them. You'll find a few Queens here for sure, but the Mini Chainsaw will be fine if you don't have any Queens on hand. Grab a "hunk of meat" off the ground somewhere and throw it at both survivors to knock them down so you can talk to them — if you take their photo before you knock them down you'll get mad PP.
Once you get them to join they'll run for the marker in the bathroom, so just follow them and provide support. Take them back to Paradise Plaza and to the security room as quickly as you can — chances are the next few calls will come during this, so answer them, and we'll take care of them once Nick, Sally, and Jennifer are safe.
Beware on your way back that the Cultists will be in Paradise Plaza, and often your survivors get overly excited and run towards them, especially the women.
🕐 5:00 "Woman Who Didn't Make It" call.
"Antique Lover" call.
"Mark of the Sniper" call.
All of those calls take place in the Entrance Plaza, so that's where we are headed. The scene for Mark of the Sniper will ensue once you enter. An easy way to kill the snipers is with any projectile, including the Hockey Sticks if you don't have any fancy machinery on you. If you need their pictures for your Psycho achievements, I recommend taking them before you kill them, because they have a tendency of not taking good photos once they've died — they often fall into walls, or just plain land face first, and then you can't get them well.
Once the snipers are defeated, go into the Cosmetics shop at the top of the escalators and get Wayne. If you want you can just set a waypoint in the back of the store, but you can take him with you too, because there are no zombies upstairs at the moment.
Head over to "Ned's Knicknackery" (E205) to find Floyd in the back. Talk to him until you get him to join. Now leave a waypoint upstairs for them and jump downstairs to find Jolie Wu in "Gramma's Kids" (E105) — she'll freak out a bit, but when you give up on her and start to leave she'll join you. While she was talking she mentioned her friend who also got stuck, so head back upstairs with Jolie to "Ladies Space" (E216) and she will make conversation with her friend. Talk to them to get her friend to join you.
🕐 6:00 Sometime during the stuff above you'll probably get the "Ronald Food Call," saying that you should bring some food back for Ronald. So if you don't have any type of food with you, grab some on the way back with these survivors — any type will do (drink or eats).
Now get Floyd, Rachel, Wayne, and Jolie back to the security room, and don't forget to grab their pictures at some point. Although Rachel and Jolie want you to hold their hands, you'll be quickest carrying Floyd and just making sure the girls keep up with you. Wayne is your only survivor at the moment that can wield a weapon, so take advantage of it. While you are there, find the room that Ronald is in and talk to him until you can give him some food.
🕐 8:30
Time now to head to the North Plaza to take care of some Girl Hunting. When you get over by the grocery store you'll have to fight Isabela — your best bet is any type of firearm so that you can hide in the middle circle area. You can kill her with the Mini Chainsaw in about 2 hits, but often you'll find that when you swing at her it just goes straight through her if she's not in the perfect spot to be hit.
🕐 9:20 You now have nothing to do until 12, at which time you will need to NOT be at the place where you're supposed to meet Isabela. There is a bathroom here to save, along with the grocery store where you could stock up on food. If you didn't go into the Maintenance Tunnels before to get that intro, now would also be a viable time to do so — just don't linger there too much, because you need to be back just after midnight.
