Mechanics[edit | edit source]
HUD[edit | edit source]
- Found HUD
- Found HUD is a HUD addition that appears on the left side of the screen that gives numerical values to the player's current stats (e.g., damage, luck, speed, devil room chance). It can be enabled through the options menu.
- It is based off of the Missing HUD mod for Rebirth and Afterbirth.
Victory Lap[edit | edit source]
- A Victory Lap allows you to start a new run with almost all of your final items after completing the Dark Room. Multiple laps can be made as long as the Dark Room is cleared each time.
- Completion Marks and most Achievements cannot be earned.
- Isaac will take a full heart of damage on all floors after beginning a victory lap (unless he has The Wafer).
- Some Items are lost upon starting a victory lap. Items lost this way are added back into their respective item pools and can be acquired again.
- If the initial run was on normal difficulty, all victory laps will be on hard difficulty.
- On the third and subsequent victory laps, the character will turn into The Lost. This version of The Lost does not get a Holy Mantle or D4. However, if the run was started as The Lost (or if the Holy Mantle was found) it is possible to keep the Holy Mantle from the previous run.
- On the third and subsequent victory laps, shops will no longer appear.
- On the third and subsequent victory laps, red chests in the Dark Room will turn into brown chests and golden chests.
- Killing any final boss aside from The Lamb will end the game, and the run will not be continued further.
Menus[edit | edit source]
Options[edit | edit source]
- Charge bars
- Added a new "charge bars" option in the menu, for passive items that need to be charged up before usage.
- This includes:
- BrimstoneTears are replaced by a laser beam that pierces through all enemies and obstacles in its path and deals high damage. Can only be fired after a short charge-up period. (collectible and Azazel)
- Cambion ConceptionAfter taking damage a certain amount of times, a permanent demonic familiar spawns.
- Chocolate MilkGrants charged tears that deal greater damage when fully charged.
- Cursed EyeGrants charged tears that can be fired in a tight burst of four. Getting hit while charging will teleport Isaac into another room.
- Lil BrimstoneA Familiar that shoots a thin Brimstone beam. Must charge like Brimstone before shooting.
- Lil DeliriumGrants a familiar that transforms into another random familiar every 10 seconds.
- Lil GurdyGives Isaac a Gurdy familiar that will charge around the room dealing contact damage to enemies. Lil Gurdy is charged by holding down a fire button and letting go. The longer the button is held, the faster Lil Gurdy will fling itself across the screen. Lil Gurdy can pass over objects and obstacles in the room.
- Lil MonstroSpawns a familiar that fires clusters of tears. Must be charged before shooting.
- Maw of the Void+1.0 Damage Up. After continuously firing tears for 2.5 seconds, a red cross appears on Isaac's head that, upon releasing the fire button, creates a black ring that rapidly deals damage equal to Isaac's tear damage to any enemies in contact with it.
- Mom's KnifeIsaac's tears are replaced by a knife that pierces enemies, can travel through obstacles, and can hurt enemies while Isaac is holding it. Holding down the fire button before firing increases its range and power.
- Monstro's LungIncreases damage and grants a charged shot that fires multiple tears in the same fashion as Monstro.
- Tech XTears are replaced with laser rings that pierce through enemies and deal damage to enemies within them. Can be charged to increase the size of the ring.
- RERUN is unlocked after completing the RERUN achievement.
- 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. Isaac will take full heart damage on all floors.
