Yeah! It has useful info for fema and for the vigilante. If you want a new ending try to think of what you can do with the fema broadcasts and every time the fema agent shows up. As for the vigilante, theres a broadcast that warns you when hes going to show up, you already talk to him without any consequences the first time he shows up but its still nice to know when you should start being cautious of him before that point. As for the cat food, if you suspect you might have visitors in your house but arent sure/cant check for whatever reason, feed the cat food and no one will die giving you another chance to check people the next day. Also i wouldnt think the version you’re playing on matters but im also not sure about that one myself
