You should try to minimize the "questionable" actions like killing or stealing and prioritize good deeds. Now it's easier for your survivors to get depressed and harder to recover. It's possible to get all "peaceful" or all "hostile" locations, but some sort of mix between them is more likely. Have in mind though that the balance in this mode is off. TIP: For even more fun try to combine it with random scenario (there's a button for that on the right bottom of the scenario selection screen). That's over 1,500 map combinations in one checkbox! You will get a couple of pre-defined easy locations, but apart from that, you're at the mercy of RNGsus. This mode though will bring all 10 locations that have multiple variations each (Sniper Junction, School, Hotel and so on) on one map, and each time variation for each location will be picked at random.
Like I've mentioned in the description of this mode, I'm fairly certain one can not reach the ceasefire in this mode. "No free loot" is a new, unforgiving game mode with only inhabited locations. You may (or may not) pick between them on scenario selection screen, as they replace old "Final Cut edition" and "Anniversary edition" checkboxes. Here's what you can expect to see in this mod:
