Something In The Way

Day 3. The worst has come to pass. I've doubled back over our tracks at least ten times by now, but every time I follow them back to our entry point all I find is a seemingly bottomless abyss...I know it wasn't there when we inserted the team into the drop point. What should've been a simple extraction turned into a prolonged firefight in mere seconds...The industrial zone we were infiltrating was an ambush. We were engaged immediately by an unknown number of hostiles and less than half the team survived the encounter. Myself, Private Apone, Lieutenant Dobson and Doctor Serra were the only ones who made it out alive. When we reached our target destination, we found the package had been...damaged. The hostages we were sent to retrieve were all dead, had been for some time. As near we could tell, something had caused their chests to explode from the inside, killing them almost instantly. With the exception of the hostiles we encountered earlier, we've seen no signs of life on this miserable rock. I managed to get up close and personal with one of them...They moved like humans, they looked like humans...but they were something else. Now we're stuck with no evac, no comms and we won't be declared MIA for at least five days. We're stuck here, just the four of us...but I don't think we're alone.
