Hi guys, during the last base defence mission. I had two aliens spawned inside a wall. I was unable to see them (just sound indicator was there) but they were able to return fire in case I decided to throw a grenade.
It was kind of frustrating, so I decided to try to move my soldier inside the wall as well. it was doable, I got ‘enemy spotted’ message but then no enemy head symbol and the sound indicator was gone.
as a result, I was unable to kill the last alien(s) and finish the mission. so after an hour of play, and checking every single corner, I had to quit.
Maybe you could add a safety trigger like ‘if aliens are unable to destroy a base part for ten rounds in a row, they lose’?
