Seeing Double is challenge #40. The goal is to defeat Mom's Heart. This challenge is unlocked by defeating Mother.

Strategy

The challenge is played as Jacob and Esau, both starting with 20/20, and Esau additionally with X-Ray Vision. Otherwise a very standard run, the challenge comes from every single enemy and boss placed naturally in rooms (as opposed to being spawned later) being doubled.

Since libraries are able to spawn in this challenge, resetting the first floor until you find one can make this challenge easier.

Notes

• Stoneys are not doubled.
• Enemies in Challenge Rooms are not doubled, as they are not spawned when Isaac initially enters the room.
