Haven't read sci-fi in awhile as I've been on a binge of progression/litrpg fantasy books. I like sci-fi but the good ones with depth are usually space operas with not so great or stagnant combat, there is only so much space ship battles i can put up with.
Right now I have the feel like i want some giant mech action or exo-suit/armors bonus points if the series has psychic powers, talents (unique powers) or a progression system of some sort. Space horror is also very much welcome!
I don't remember all the space series I've read but I know I can count out
Expeditionary Force
Luck's Marines
Galaxies edge

Iron Widow by Xiran Jay Zhao
You might like Iron Prince by Bryce O’Connor and Luke Chmilenko, it has that progression system with powered suits and strong combat focus. Old Man’s War by John Scalzi is also worth a look for the enhanced soldier side of things. If you want something darker, Armor by John Steakley leans more into the psychological side of powered combat.
