Gameplay alteration! Big rooms do not show up as big rooms on the map unless you have some reason to know that they're big rooms - entering them, for example. The Map allows you to see them in advance for obvious reasons, and the Spelunker Hat allows you to see them in advance thanks to "sees through doors". Otherwise, though, you have no idea before you enter a room whether it's a big room or not.

The Lake Of Fire
Tougher variant of Sheol + The Dark Room, unlocked by having all achievements relating specifically to Sheol and all achievements relating specifically to The Dark Room. Has a chance of spawning instead of Sheol if you have the Negative when you enter the portal to Sheol; this chance is akin to that of spawning the Cellar, Catacombs, Necropolis, or Utero. Always an XL floor but may have other curses as well. As is standard for an XL floor, there are two bosses fought in consecutive rooms; they draw from a pool that includes Super Satan (not to be confused with Mega Satan), End Times Factory (big-rear end machine with a ton of health that spits out random Horsemen and Sins), You're In Hell! (modified version of Isaac that turns into modified version of ???/Blue Baby when killed the first time), Chaos (giant Loki that spawns regular Loki and Lokii), and True Buddha (once he's unlocked). Also contains a locked door to the Mega Satan fight, as The Dark Room does.

The Promised Land
Tougher variant of The Cathedral + The Chest, unlocked by having all achievements relating specifically to the Cathedral and all achievements relating specifically to The Chest. Has a chance of spawning instead of The Cathedral if you have the Polaroid when you enter the portal to the Cathedral; this chance is akin to that of spawning the Cellar, Catacombs, Necropolis, etc. Always an XL floor but may have other curses as well. As is standard for an XL floor, there are two bosses fought in consecutive rooms; they draw from a pool that includes The Boy You Should Have Been (buffed Isaac), End Times Factory (big-rear end machine with a ton of health that spits out random Horsemen and Sins), Mom And Her Heart (exactly what it sounds like; fight Mom and Mom's Heart simultaneously; they're procced as the same boss so the pieces don't harm each other), Lambs (Double Trouble version of the Lamb fight), and Zeus-Thor Tag Team (once they're unlocked). Also contains a locked door to the Mega Satan fight, as The Chest does.

Idolatry
"The false gods are loose in the basement!"
Achievement obtained for entering the portal after the Mega Satan fight (more on where it leads in a later post). For the portal to appear at all, you must have defeated Mega Satan on a previous playthrough as the same character. Unlocking the achievement unlocks several new bosses, two of which are obnoxious as gently caress.

Buddha/True Buddha
A misinformed fundamentalist Christian view of Buddha in Edmund's signature style. Shares some similarities with Peep and Mega Fatty. The regular version may act as a boss on most floors or as a regular enemy on late floors, while the stronger, "True" version adds variety to the Lake Of Fire boss pool. Neither version is strange in its difficulty.

Zeus/Thor/Zeus-Thor Tag Team
Reskins of each other with some similarities with the final form of War, though with a ranged boomerang-style attack in the form of their lightning/hammer. The regular versions may act as bosses on most floors or as regular enemies on late floors, while the stronger, teamed-up versions add variety to the Promised Land boss pool. No version is strange in its difficulty.

Golden God/Platinum God
Enormous, immobile bullet hell bosses that look something like tikis. Golden God has a (very slim, on the order of 1%, though higher in Hard Mode) chance of replacing an item room, akin to what Greed/Super Greed does to shops or what Krampus does to devil rooms. Platinum God has a higher chance of replacing an item room, on the order of 10%, but will only do so in the first place if Golden God appeared earlier in the playthrough. Neither boss drops anything; they screw you out of an item room. Hope you have a teleportation card or item on your person when entering item rooms. Players will hate their guts; the bosses even tell you to stop playing as you fight them (alluding to the old startup screen on BoI). At least killing Platinum God gives you the Iconoclasm achievement. Unfortunately, the Iconoclasm achievement unlocks the Iconoclasm item, a spacebar item that acts kinda like a reroll-all-of-your-items button, except that it doesn't give you any new items; it just takes away the ones you already have (including Iconoclasm itself). Doing so actually really helps you out with a later achievement, though.
