Okay, having played 11 hours of Shadow Warrior 2, I find that it's basically Borderlands with a better movement system, which is really exactly what I wanted.
Lo Wang's ability to double jump, airdash, infinite sprint as fast as a car, and land from any height while shooting his guns with no loss of accuracy is amazing.
Disclaimer: the following is based on my having cocked around in the game at the highest difficulty level for about 24-ish hours and is largely a consideration of combat gameplay. With that out of the way...
Yeah, the ability to move like a Warframe is down-right essential. Sadly the various tiles that comprise the sets from which a level is constructed aren't always uniformly conducive to not crashing into, or getting stuck on, shit like a dumbass. I'm looking at you, anything with steps.
I've had a few bugs which have phased me through the map and/or into terrain when moving at SHADOW SPEED, but thankfully it's pretty unusual. That, and occasionally the game will chug like fuck when there's a lot of mobs on the screen; I've had a couple of 5-15 second long freezes when the hordes of the Shadow Realm have swarmed me. Also time-to-kill can be hilariously long without the right gun or gun setup, and on a very related note jewels being randomly dropped and influenced by difficulty level is kind of shit if what you have leaves you deficient in particular fire-mode changes, damage boosts, or elemental upgrades. 3 slots per weapon (especially given that some weapons automatically lose a slot due to innate affinities), plus one for amulets and one for armour, is kind of limited and limiting, but that's a doubled edged thing which I'll get into below. The prices of a lot of the weapons, especially initially, are downright silly, likewise the various jewels and amulets. Ammunition is also kind of frightful to restock on in full, so what I usually do is go to the earliest free-roam mission and dick around until I find a purple demon lantern statue and restock there, then 'port out. Bit fiddly.
Speaking of fiddly, modification is the elephant in the room, and whilst it isn't implemented flawlessly here, it does at times shine. The menus, which are at first a bit tricky, allow one to relatively change elemental affinities in the middle of a gunfight to suit the task at hand, and having to really think about how to use those 3 or 2 slots in the heat of the moment is actually pretty compelling. Conversely, build your guns with crap mods and you will have a very slow and unpleasant time of it indeed. Systems mastery is definitely rewarded here, even if attaining it isn't terribly well laid out for those who haven't encountered the like before.
Melee is also kind of shit at high difficulty unless you really spec your skills for it and get used to darting in and out of attack range like a tick on yabba, and even then it's really easy to get pinned against terrain or a precipice because confined spaces are fairly common. Additionally, it's really easy to charge at a mob with a special attack readied, and 'glance' off of them as you strike, wasting the blow and the second or two it took to charge it up. As to player death and it's frequency, well. Generally most enemies have a wide range of movement and attack options, and they use them aggressively and predictably. This means that unless and until you learn what they do, you're going to die a lot.
I don't mind this, per se. I don't mind losing cash on death, and I don't mind losing Fury, but depleting my whole Chi bar and rejuvenating every mob back to fighting fettle in an instant? Come the fuck on. Until you have regenerating health and high chi regain, a string of deaths combined with inadequate weapons and weapon mods can really stymie progress in a super un-fun way. Thankfully the game showers you with drops of all kinds, and farming enemies in previous levels to build up a warchest is actually kind of fun in this game.
Why, you ask?
Broadly, because Flying Hog got the meat and potatoes right.
The combat really delivers. The guns are, once you unlock some decent mods, amazing, and they only get better as you unlock more. A great many remain viable until later levels if modded well, and there's basically something here for a wide range of play styles, even for people who like to engage at some distance. There is, of course, an absolute smorgasbord for anyone who wants to get in close. I've found that properly built shotguns are, pound for pound, the best burst damage dealers in the game, and combined with Lo Wang's speed and accuracy, the feeling of flash-stepping around with 3 barrels of DOO-whoops wrong franchise-WANG is just fab. High-DPS-high-ROF stuff like rifles, nail guns, and machine guns, can be difficult to hit with if you're bounding around, but that may just be me. Explosives are great when they work, as are melee weapons, and the special stuff is bonkers. Flaming power fists? Laser chainsaw katanas powered by soul energy? Bows? Say no more, Larry and co. (that's your arms dealer shop guy) have got you covered.
Movement is, with the above exceptions, pretty great. You're fast, you're agile, you can't take fall damage, and you can climb and jump generally very, very smoothly, which is essential when running the fuck away from packs of dudes. Given that most of my experience has so far tended to consist of doing just that until I could find favourable terrain to help reverse the flow of a fight, Wang needs to move like greased lightning, and boy does he ever.
Aided by the generally excellent movement, melee is a high risk, high reward sort of deal, which I've largely eschewed because guns at later levels do outshine much of the cutlery that is presently available to me. That may change based on what I can find, natch. At lower levels chopping fools up is a simple but brutal affair that's hard to pull off and equally satisfying when it works. The swordplay also synergises really well with the gunplay, as one might hope, and together they produce an experience that's a lot less linear than, say DOOM 2K16; madcap, occasionally balletic, furiously quick and never less than tense when all cylinders are firing.
Basically the core of the thing is flawed in places, but the actual shoot-mans-with-shooters bit is first class and a lot of fun once you work out what goes where and what works for you.
