This is one of those tidbits you might have liked to know while streaming this instead of days later when you probably are already finished or almost finished with the game (and maybe you discovered it already?) But, in the options menu, you can set the hotbar to "standard" so that you're not limited to having only 4 weapons in the slots/number keys with 3 explosives and 3 consumables hogging the rest of the # keys. (Also you might already know but might have wanted to know back when streaming this that flechette shells for the shotgun are actually meant for armored (i.e. robots) enemies more, and dragon's breath shells are for more organic ones with the incendiary feature but very low armor penetration.) (& that soda, snacks bars and chip bags are also consumables, you can "use" them, drink/eat for a bit of health, then vaporize the empty bags and wrappers etc.)
Super behind on watching these because I'm only watching the episodes after I finish the stages/areas but man this is probably one of my favorite Let's Plays ever. This is really great stuff
