Also I have this screenshot. Many, many Holy Bricks were made during that day, I am sure. Never saw such "invasion" again ever since. Must be a glitch in the map generation. Why would those two Grineer spaceships spawn so close to the ground, and to each other?

P.S
The "alien crossbows" are amazing, I love them. I use the two types that use the standard bolts and the Ballista. Very kakkoi.
