I've spent the evening playing the latest in the sea of Warhammer (40K) games, Mechanicus. Take a squad of Adeptus Mechanicus tech priests on a romp through choose-your-own-adventure type scenarios and a bunch of turn based tactical combat (lazy comparison: x-com-like) as you raid their tombs for science and the Omnissiah.
Seems like one of the better ones so far, though we'll see how I feel after more than one evening's play.
Plenty of customisation options between many item slots (the usual head/arms/legs/etc, plus extra slots for servo arms and the like) and a choice of 6 skill tree paths for each tech-priest (with the option of going deep into one or two, or shallow into lots of them). At the start of the game you only have 2 tech priests - I just unlocked my 3rd priest on something like my 4th mission. You can also unlock and bring along non-tech priest troops as support and cannon-fodder, with different types unlocking as you go (so far I have basic Servitors, Skitarii Rangers, and Skitarii Ranger Alphas).
There's a need to balance between raiding every room in the tomb to try and get max gains (though that can backfire and actually do you harm), and, well, not doing that cos it'll wake the Necrons up faster meaning the battles will be harder (as they wake up they get buffs to initiative, movement, reanimation time, numbers etc) and bringing the end of the game closer - there's a doom clock that advances faster if you finish missions with high Necron alert levels.
It's also got a somewhat novel action point system - in this game they're calling it Cognition, and it's a shared pool rather than each unit having its own action points. The Cognition pool doesn't refill on its own each turn, you have to acquire it through e.g. scanning Necron obelisks, examining their corpses, your Servitor troops being attacked (collecting data from their wounds, heh), and so on. Not everything requires Cognition - you can do basic movement without it and some of the weaker weapons don't require it, but it does present a number of tough decisions as the fights heat up.
