Meh, the deathray was ridiculous - they could nuke buildings and vehicles between you and them from a long range, where you couldn’t see them.
“Driving along, being very careful… oops, I came within 50 tiles of a space I can’t see, and there was an eye there, so now I’m dead.”
You’re the first person I know of to consider that good game play.
It actually didn’t do any direct damage to the player, but it instra-destroyed building and vehicle tiles all along the way. Since they could see through everything, they could easily use it on you while you were hiding in a building (building falls down on your head) or driving along, say, on a road through a forest - hope they don’t hit the tile that holds your fuel… BOOM.
So, as long you stay entirely out of buildings and out of the blast radius of all fuel tanks, and never wanted to have a vehicle that you put any effort into, they were fine. :-/
