I’m really enjoying the new z-level stuff, on the whole, but there are a few shortcomings:
-it appears that turrets sometimes shoot across z-levels in labs - I find zombie corpses in places where there was nothing to kill them, and the animations suggest so, as well.
-holes that zombies can fall through are great, but the interface doesn’t seem to give any indication of where those holes actually are, especially not from below. It also seems to be impossible to view other z-levels, even when you should be able to see them (looking down off of a roof, for instance).
-barring really good luck or the occasional closed loot area, lab loot rooms are almost impossible so get to in time to save to loot from exploding secubots. This is both silly (secubots shouldn’t run over the dissectors in the room they are set to guard… and why are there even dissectors THERE?!?) and exceedingly frustrating. admittedly, this is both a z-level thing AND an “explosions are broken” thing, the latter of which seems to have been improved in recent experimental builds (yay!).
-“vehicles” that span z-levels should now be possible. Yeah, that’s a big order, I’m sure, but it would be REALLY nice for non-vehicular vehicles (solar arrays to provide power in stationary bases, for instance)
I can think of a few other things along the lines of that last one, but that’s really additional new features. On the whole, it seems to be progressing very well - thanks devs!
