Day 33, 34, 64 | Walkthrough Firewatch Guide

The amount of supplies that you take with you does not matter.

After the day starts, go straight into the supply drop zone. In the crate, you find food - you can take either only food prepared for you (the middle row), or take it all.

Note: The cutscene on day 34 will play only if you have taken all the supplies from the crate. On that day, Delilah asks you about supplies that you have taken. You can try and hide the fact, but the truth will become apparent anyway, with no further consequences.

If you want to, you can name the fire.

On day 64, talk to Delilah. You can either say that you are interested in her being with you, or keep silent about it. Also, remember to take a look at the fire before that and to name it.
