The main menu with the RERUN option active
RERUN is a menu option in Afterbirth † unlocked after completing the RERUN achievement (Complete three Victory Laps and start the fourth).
After winning a run the
Continue option in the main menu will be replaced by RERUN. Selecting it starts a new run using most of the previous won run's items.
Notes [ ]
Isaac will take full heart damage on all floors.
Except Greed Mode, where all damage is always counted as half a heart due to its mechanics. It may not be necessary to start a 4th lap to complete the achievement on some versions/platforms. Even if an extra lap is started, it may be quit immediately.
RERUN cannot be used multiple times in a row. After beating a RERUN, the main menu option becomes
The run with the last character can be relaunched only via defeating
The Lamb and starting Victory Lap. After ending a Victory Lap in any way, the option in the menu is still Continue. RERUN is counted into the win streak.
Achievements are disabled for RERUN. RERUN can be used to start a new Greed Mode run, but the Greed Machine will not appear after defeating Ultra Greed.
Bugs [ ]
Starting a RERUN with Schoolbag and two active items may copy the item in the "first" slot to both slots.
Switch Winning the run with The Soul instead of The Forgotten will start the RERUN as The Soul without any chains connecting it to The Forgotten. Switching back to The Forgotten returns everything to its normal state.
