Welp, I took the plunge after selling enough stuff on ebay that I could use paypal money to pay for it on steam.
There are three classes currently:
Crusader,
Assassin,
Psyker
Each of these is split into three also
Crusader gets (I'll go off memory)
Sword and board (armour and clobbering stuff - I forgot to check the secondary weapon)
Tactical (mine, it comes with dual laspistols and an autogun)
ranger focus (shotgun, lasgun, and some sort of back mounted frag launchers that look suspiciously like terminator cyclone launchers but apparently aren't).
(male only, tough voice, etc, so I didn't seem to get any customisation here.)
Assassin has:
infiltrator (close combat with blades, not sure on secondary weapons and a power sword, can turn invisible)
sniper (rifle and pistol, can make holographic copies and set mines)
some other lunatic one with sniper rifle and another rifle gun a shotgun, moves fast
This one is all female
Psyker gets...
well, three more I didn't look too closely here, so maybe I will later, but my assumption was varying psychic powers.
A) a force staff, doesn't say what else
2) force rod and a power sword
iii) bolt pistol and force rod/staff - this is my second character now, and would have been a better fit as Jack, but is now "Julius".
gameplay is very diablo ish, point and click to move, point and click to shoot (errr, wait, what? why are my shooting and movement controls both bound to mouse?) which often results in my character departing cover after killing something. I'd prefer wasd for movement, and mouse for aim and shoot, even if this is "ARPG" at pseudo-isometric view points.
Other keyboard controls are used for additional actions and things like grenades, health packs, etc.
E: thankfully, there is a nice menu for editing controls, so it's the work of mere minutes to fix the awful standard version of the controls into something much less ridiculous when using a keyboard.
My irritation with control systems aside, the atmosphere (I'm only on tutorial missions) isn't too bad. I think the main theme music is too "up" (which I'm blaming on the brass section), but the in-game music is much more nefarious-sounding.
Overall it seems to have a good theme for graphics (pretty damn good) and music (also reasonably good), and the writing so far doesn't seem to be truly shocking - but then I tend to give too many things the benefit of the doubt, so make of that what you will.
Actual art design for the three characters themselves is pretty good, and seems fitting for the universe.
My tactical crusader looks reasonable for someone of an inquisitorial nature, and I'm really liking the helmet. Makes me wonder if my 28mm version of Interrogator Jack Jomar really needs the faithfully duplicated version of covenant's head at that scale - maybe he could be wearing a helmet for 28mm? On the other hand, how noticeable are dudes with helmets in the 41st millennium in civilian life?
I'll keep digging, and see what else I can turn up without ruining anything.
ANOTHER EDIT:
Okay, voice acting - it's not bad.
NPCs calling in to you get a video screen pop up in the top right DoW2 style, and the video similarly does not synch up to the speech, much like in DoW2.
My character has a deep voice (deeper than I'd pick), and sounds suitably difficult to place, such that he could have any sort of build, history, etc. Appropriate for someone behind a mask.
I'll consider maybe making an assassin to hear the female talent - not sure which to pick though. Sniper, infiltrator, or the murder one (shotgun/sniper). I'm leaning towards either invisibility and stabbing, or ranged shenanigans with a sniper rifle.
I'll also eventually check out my psyker choice at some point.
