All the shields can be taken down with any weapon, you don’t need anything heavy. I’ve been taking them down with sickle to then one shot tripods with quasar aiming at where their legs connect to the body or just throw a grenade in to landed UFOs open hatch. Haven’t figured out where to aim on flying UFOs to one shot the with quasar yet.
If I’m not listening to music or hyperfocusing really hard there’s a constant looping snippet of some random song playing almost all the time, usually just a few seconds long. Changing it requires to listen to something else. I don’t really mind it (as long as the song doesn’t suck!), seems like my brain just needs a constant rhythm throughout the day. I always thought that it’s normal for everyone until I learned about neuro divergence a year ago.
