Batman Doom

Batman Doom is a total conversion for Doom II, created by ACE Team. In Batman Doom, the player plays as fighting various criminals in Gotham City. The game includes a very complex DeHackEd patch which makes it very different from Doom.

Tricks
Batman Doom is famous for a large number of both DeHackEd and mapping tricks used in it:
 * Moving train
 * Flying helicopter
 * Killer Croc picks up rocks
 * Gang fights
 * Huge explosion

Bane
Bane is the final boss of Batman Doom, appearing in MAP30. The player must defeat Bane using the 7th weapon, which can be picked up at the start of the level (the words "fight only with these gloves!" appear). If the player switches to a different weapon, the words "you failed to fight Bane with your fists" appear over the screen, leaving the player with no weapons and defenseless against Bane.

Bane has 250 hitpoints (the same as the Doom II final boss). When killed, the level ends.

Compatibility
The TC is designed to be compatible with vanilla Doom and is available for both PC and Macintosh. However, a bug in DOS DeHackEd means that it does not run properly in vanilla Doom (after switching to the fist it is impossible to switch away). A patch has been created to allow Batman Doom to run in vanilla Doom properly.

Several fixes have been released to run Batman Doom properly in modern source ports. A ZDoom version recreating the DeHackEd gameplay modifications with DECORATE is linked below. Crispy Doom can run both the original version and the slightly fixed one (not displaying the unneeded episode selection menu) without the aforementioned fix for vanilla Doom.

The GZDoom-based graphical overhaul of Batman Doom named is in the works.

"Lost" Mac Molotov Cocktail Effect
Due to the aforementioned DOS DeHackEd bug, ACE Team decided to recommend Boom as the preferred PC port upon release. However, this inadvertently caused the Zeke character's Molotov Cocktail attack to crash the game, forcing them to simplify the effect for the PC version.

In the original Mac version, the Molotov attack spawned a large number of flames by using a recursive loop of the Pain Elemental's death code pointer. Each flame (a modified Lost Soul) called the PainDie code pointer, which, in turn, spawned three more flames. This was limited by vanilla Doom's hard-coded limit of 21 Lost Souls - after the maximum number of flames had appeared, no more would be spawned.

Since Boom removes the Lost Soul limit, this effect now caused the engine to crash. ACE Team simplified the effect by only spawning a single flame instead.

The original effect was only rediscovered in late 2018. Since PC vanilla Doom compatibility was restored with an earlier patch, the original Molotov effect is once again compatible and a new patch restoring it was created.
