We see a hidden kite ship. We go to board and it's a German/Martian ship. They open fire.
We reduce their ship and they strike their colors. We collect their weapons and move on.
We find the entrance unguarded. Actually blood smears. And bloody boot tracks. And dead Martians. Actually one of them is till (barely) alive.
As we travel down the corridor, we run into a bunch of martians.
We kill them all
