Tl;dr It's fun, but punishing.
Let's call the genre "Stamina Pattern Combat" or "SPC". So, like most all SPCs, it's very obviously inspired by the SoulsBorne series by From Software. That alone gets some idea for how the game plays. So, I'll just do a pro's and con's list to help making a purchase decision:

PROS
+As long as you read the floating UI, the game has a tutorial zone that explains basic mechanics.
+Armor and weapons are split into 1 of 3 or 6 classes respectively, thus setting a good expectation of how you're play style(s) will work.
+Armor and weapons have enough detailed stats that you can min-max builds.
+You can further customize your build using implants of various effects. You'll have to look at a wiki to see them all.
+Implants and their buffs/quantities stack with more copies.
+Loot farming is much simpler than other SPC games I've played; You want it? Cut it from their cold, dead, metal hands, arms, legs, or heads.
+The longer you go without using a safe area, the more you're rewarded for your skill/brazenness; The game increases a scrap(money) multiplier that goes up the more you have on you and the more you kill.
+You can bank/store your scrap in the safe area, resetting your multiplier, but saving that scrap for later.
+Jumping is easier than in Dark Souls
+Having a full set of a given armor name (ex Wearing the head, arms, legs and chest of the Lynx armor) will give unique buffs

CONS
-Basically all enemies can wreck you; You can walk around a corner, be surprised by an industrial hammer to the face, and then be loading back into the safe area before you can complain about balance issues
-It's incredibly easy to lose your way in many of the environments. Very interconnected, but not enough distinguishing landmarks to really remember.
-It's also incredibly easy to forget or never know what your goal is and why it's a goal
-Many enemies have poor telegraphing of attacks
-Blocking is alright, but you can't move while doing it, and there's only a very poorly explained/implemented counter-attack mechanic
-You only have a limited time (a bit over 2min) to reclaim your stuff after you die (but kills along the way add to the timer)
