There are a few things you missed in Higgs, the key was in the birdcage on the desk upstairs, there was Kline’s scrubs on top of a dresser, lots of things are hidden in this dlc, I think Kline’s glasses are back at the think tank, you should dress up with all his named gear also möbius as well
You can store your extra gear at the sink, there are lots of things you will want to pick up along the way, and definitely explore all the locations fully, there is a cave just north of Higgs village with some good lore that is easy to miss
Good choice leveling up Science and Melee, both are very useful in this dlc. But don't neglect Energy Weapons. You haven't encountered robots yet, but energy or melee weapons are the most efficient way to kill them.
