Strategy[edit | edit source]
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[edit | edit source]
- Stoneys are not doubled.
- Enemies in Challenge Rooms are not doubled, as they are not spawned when Isaac initially enters the room.
Unlockable achievements[edit | edit source]
- Broken Glasses - Complete Seeing Double (challenge #40).
