You are an original military man,but your ship crashes in an unknown planet and theres no signal,just wen you think things can't get any worse
you fall into a pott whole
and your G.P.S. says your 300
stories underground!.
Then you find out there's ZOMBIES in that place,find the key room,a small room with a teleporter inside and get to where they park there ship but be carful on your way...
Your commander
