I've noticed that some types of cover in the game are completely indestructible. One example are cars. While you can blow a car up, it won't actually destroy it as a piece of cover that you or enemies can hide behind.

I've also noticed that some types of trees actually require more than one action to completely destroy as cover. An explosive will reduce the tree down to a stump (which still counts as high cover), while a second explosive will finally destroy it completely.

Are there any other types of unusual cover in the game that are effectively indestructible, or that require special actions to destroy (like attacking it more than once)?

    I don't know how indestructible cars are. I once had a car blow up so hard that it took out the lamppost next to it, and there was no husk of the car left, either. Of course, that could also have been a bug. Feb 11, 2016 at 0:15
  • Hmm, I liked the XCOM 1 mechanic better, where a fullcover tree became a low cover stump after it was hit once.

Actually "full" trees are destructible, and have 3 stages before getting completely destroyed.

1: unharmed
2: 1st hit - full cover trunk, full tree size
3: 2nd hit - full cover trunk, human (or 1 story/floor) size
4: grounded - no cover


There are some alien structures in city center type maps that don't seem to care if I hit them with grenades. Not only do they get not destroyed or damaged, they block the area of effect of explosives. Much to my chagrin when a muton taking cover behind one took no damage from a blaster bomb. The kind of elongated black inscribed blocks are one. There was another alien pillar thing as well but I don't remember what it looked like well enough to describe one.

  • Actually, the types of pillars you're describing are vulnerable to explosions, but for some reason only at specific angles. They seem to be bugged pretty hard. Feb 22, 2016 at 23:46
