Memo
(Hopefully not my last...)
We were attacked by these... things, they're hard to describe. They almost looked electrically charged. We understood that going towards that storm would be dangerous but, hell, you can't expect that. I've got to find where the other group have set up camp and make it there, but I got a lot of land to cover...
If you find this note on my corpse, please take care of my cat. She doesn't deserve all this shit and she's not picky with food so you won't have to worry about her. Just give her some attention every now and then.
