RESIDENT EVIL RESISTANCE

Best way I've experienced this being done is to have the Mastermind stay in their map the entire time, spawning no monsters or switching cameras, just staying in the map, guiding Survivors to the key items and back to the door in the first segment, to the security zombie and then to the security consoles and then the door in the second segment, and then to the ACTIVE bio tanks and then to the door in the third segment.

In the first segment, the keys show up like old handcuff keys on the map. In the second segment, the security zombie shows up as a blue skull wearing a police officer's hat, and the security consoles appear as they do in the game, but as a photo icon of the consoles. In the third segment, about five bio tanks spawn, but ONLY the one in red is the ACTIVE one.

Also, the Mastermind should call out traps and monsters in the Survivors' paths while giving directions to key items, security zombies and consoles, active bio tanks, and escape doors.

The team I worked with today escaped in about 07:32, almost two and a half minutes to spare, hopefully those reading this guide can do better, or at least get the achievement, best of luck everyone!
