The Imperium didn't like failures. All around us among the smell of spent heavy bolter cartridges and plasma was the battlefield was littered with the remains of the latest alien assault on our bunker. The lifeless piles of rotting alien flesh made no difference to the Tyranids though they would just make more. We couldn't afford the casualties either. For every fifty of their we killed they took down one or two of our boys. Those would normally be good odds and the men died bravely but the problem was we weren't fighting chaos or eldar we were fighting the Tyranids.
This damned rain! It was wet and the rain was a constant reminder of the Emperor's irritation at our inability to correctly judge the presence of the Tyranid attackers. Squaddy Ryanah had just finished decapitating the genestealers and interrogating the cultists but so far we had no answers. To make matters worse the Librarian shebitch Marlane was slated to land in about an hour. I was screwed. I needed to find the reason that the tyranid attacks never made any damned sense.
