Can someone explain how vision and line of sight works?
So I don't mind missing 3 60% shots in a row on something you really NEED to kill, sure it might make me twitch at times, but I took the gamble and it didn't pay off, it's a chance game so deal with it.
But what really irks me is when something shoots me through a wall that it can't see through. It's happened twice recently in missions where an alien will have 0 vision of my character theoretically, but shoot through a building, to destroy the wall of the building where my character is then just killed as it's facing a squad solo, I wish I took a screenshot now, but here is my best MS paint interpretation:
So in the below, I'm on the intercept a UFO mission, and so I clear up the outside enemies, start approaching the UFO, I've got a ranger there who opens the door and finds three mutons, can't really deal with that immediately, so I setup the squad on overwatch, and as there is no high cover in site, I hide the ranger in the corner near the door I just opened (not next to the door as could be seen, in the corner 2 tiles away from the door), hoping to be able to get my ranger close as I don't have run & gun yet.
Imagine my frustration when they just shoot through the wall, hitting my ranger and removing his cover, and the follow up attack kills him, THEY CAN'T SEE HIM THERE IS A WALL IN THE WAY!
I figured I was just a bit unlucky, until I tried the same trick on an alien facility map, and the exact same scenario happened again, I got lucky in the fact the cover wasn't destroyed, but he just outright shot through the wall of the building which they shouldn't be able to see through.
There were no windows or transparent walls that they could see through, unless it's like a one way fancy alien material thing I'm unaware of.
Is there some kind of overlay that allows you to see your vision and the enemy vision? Or if not a mod that does this? Or perhaps a good explanation that helps me play a bit smarter in this way?
