Which types of doors can be destroyed by genestealers, and when? Just ran up in a mission where a Librarian (secondary objective) is surrounded by 3 doors that show the yellow computer symbol / red door. So only 1 door to get to him and he has 7 fields of overwatch ... impossible? I destroyed computer consoles because I thought that might open the doors but nothing happened when the consoles were destroyed.
What we also need is basic rules like how does line of sight work, can a Terminator attack in melee diagionally, how do enemies spawn (I get the feeling that it costs them resources to change the spot where the genestealers spawn, but that is just a feeling).
Especially line of sight is something that I don't want to find out via trial and error. (shooting straight works of course but if you are in a corridor looking at a corridor that is orthogonal to the first with big rooms adjacent I got some fields in Overwatch that I wouldn't have thought covered by it.)
Oh, and things like "What happens if a Terminator dies". I was super afraid of losing all upgrades (which felt unfair) when losing a marine and always saved / loaded until I realized that you don't seem to lose upgrades and so on if a Certain marine dies (correct me if I am wrong, because there is no info on that too).
I also just registered to ask for this. We need a manual. Not everyone knows the board game's original rules (I know, I'm a heretic). Some things have to be learned by trial and error and with such a slow pace in the game it is a real pain and not fun to find out things this way. Please create some hover-over info for EVERY symbol there is and doors, rubble and so on.
