Clang! 
 
 The noise echoed through the hexagonal corridors and the lights went out. Seconds later a backup kicked in and a soft green glow light up the corridor from small squares in the floor plating. 
 
 I glanced up from my desk, and rubbed my eyes. Id been staring at these samples for too long now and the last thing I needed was for a repair on my rota. 
 
 I picked up my coffee mug from the desk and grabbed a torch from the emergency box by the doorway. I had hardly made it three metres down the corridor when I heard the base alarm sound. 
 
 Containment breach in sector three. Atmosphere condition critical. I glanced at the wall designations to confirm my fears. Sector three. I ran down towards the exit, my torch throwing shapes up on the walls as I ran. 
 
 I turned the final corner to see the bulkhead door sliding closed, the amber lights flashing here. I hammered on the door and looked through the small porthole. 
 
 `` Hey'' `` Open the door'' `` Im still in.....'' 
 
 I stopped short. I was frozen on the spot and my mouth dropped open, my mug slipped from my fingers, its contents long gone from where I had been running. 
 
 I ran my fingers down the glass. I should have been looking through into the canteen area. But it was gone. just a few tables sat out on floor tiles. The rest of the walls, ceilings and the rest of Mars base echo was gone. 
 
 I turned round and slumped towards the floor. 
 
 The amber lights at the door stopped flashing and the alert annouced. `` Sector Three Sealed'' Repeat `` Sector Three Sealed'' 
 
 I crawled over to the terminal near the door. I placed my hand on the screen and the monitor danced into life. I scanned across base map. There was n't much here, just some labs and an airlock to the EVA buggies. 
 
 Clang! 
 
 It echoed again. 
 
 This time it sent shivers through my body. I was the only one here now. I shone the torch down the corridor and started walking slowly down. The emergency lights did n't give much light and there was no sunlight coming in from outside. 
 
 Clang! Clang! Clang! 
 
 This time it was to my right. And I knew what it was. I leant against the wall and my heart dropped as my suspicions were confirmed. Something was knocking on the wall. Something is outside.
