Currently the WR holder for Binding Of Isaac: Wrath of Lamb, is incorrect. The game being played is either Binding of Isaac: Rebirth or Afterbirth. It is incorrect for both the chest as well as the sheol category.

The enemies he is encountering as well as the ammo he is using are both not available in the base game, they were added later on in one of those two other games as mentioned above. The run was submitted and verified by the same user. Im sure its just a mistake and he submitted it to the wrong game but I dont see any way to report the run.
