Here's another side quest that I did that I randomly stumbled upon lol. This was pretty easy except for the fighting part. Unlike the Mother's Day quest there was no need for platforming.
I collected an airdrop at night as well and it landed at sea so I had to swim. Thankfully the volatiles can't swim lol.
I found the EXPcalibur as well which is an easter egg weapon that has a really big damage. I had to hold 'F' for 9 minutes just to get it. 🙄 I tried it after but then it gets damaged so easily so it wasn't worth using it on some random enemies unless probably in a hard quest.
For the side quest you just have to get the thing at the back of the car and I didn't even have to kill this thing. It was slow so I was able to get it before he got close to me lol.
