This trophy is not influenced by who'm your survivors are near the end of Chapter 10.
At least Mike and Same will end up in the lodge where a cutscene starts with the Vertigo showing off some rooster behavior
.
After Mike breaks a
light bulb. Sam will get the option to save 'someone' or run for the switch (depends on your survivors).
Immediately run for the switch (basically, the first time you're asked to run for it, scream with everything you have left in your lungs and go for the 'switch' option
.
The video belows might give you a bit more context ;). Good luck!
