As such, none of these walkthroughs are a fail safe 100% guaranteed success on your first attempt but they have all been thoroughly tested and passes were achieved with the requisite number of biohazards on completion at least 70% of the time. You can do them in any order you like but the guide walkthroughs are listed in order.Īs with the main game modes and as advised in the main Trophy Guide, random events can and will happen and they can really throw a spanner in the works.

The rest are all locked, but they all unlock by beating Black Death on any difficulty no matter what biohazard rating you get so it wont be long until you can pick and choose what to do next. I will provide very detailed descriptions and screenshots to accompany many of the phases you go through in each scenario but for your own sake, save these until after you've at least beaten the main game with every plague type so you know generally what you're doing.Īlso just something real quick is that only 2 scenarios are playable from the beginning, Santa's Little Helper and Black Death. This guide assumes that the player is not only familiar with things like the gameplay mechanics and various screens, but has unlocked a good amount of trophies from the rest of the trophy list. Before we delve into the scenarios, here's some general things to cover: For this trophy we need to complete each scenario with a 3 biohazard (the equivalent of a 'star' I guess) rating. These scenarios are developer made situational arenas which have additional factors when compared to the main game, some make it harder to manage and some are just fun and interesting new takes on the same formula. Welcome to my Supplementary Guide for the Official Scenarios, a strand of game modes playable in Plague Inc: Evolved.
