scp-2000 is a giant unknown cave.
if two d-class enter the cave it looks like a red cave.
if one d-class enters it looks like mars but the d-class is on Mars.
the d-class now looks like scp-173 and scp-096 but in the same body.
when a guard enters the cave nothing happens to him or her but the d-class.
you must have a level 5 key card to go in scp-2000 termination will begin 2 days after this.
that is all we can say for this scp hope we get more intel.
