Doom II: Hell on Earth (Game Boy Advance)

Doom II: Hell on Earth
Also known as: Doom II Developer: Torus Games Publisher: Activision Platform: Game Boy Advance Released in US: October 28, 2002 Released in EU: November 15, 2002 This game has unused graphics. This game has unused sounds.

The classic PC game hits handhelds, with some annoying censorship. Weirdly enough, unlike the GBA port of the first game, this one doesn't actually use the Doom engine at all! Mainly due to the much bigger maps of the game, an engine specifically made and optimized for GBA (Southpaw engine) had to be used.

Unused Graphics

John Romero's Head

The John Romero head hidden behind the wall in the Icon of Sin is, in fact, still present in this version – with, of course, the blood made green per the censorship issue. Due to the lack of a no-clip code, the chamber isn't normally accessible, However, if you run up to where two walls join for at least two minutes until you clip through a wall, then Romero's head can be seen off on the distance! Another way to access this is with a patch code to set the player's coordinates inside this area.

Mug Faces

There's a ton of unused mug faces in the ROM! Let’s begin.

Since cheats can't be activated in Multiplayer and since the Invulnerability power-up doesn't even use this animation like on PC, these are completely unused without some kind of patch code.

This port surprisingly doesn't use the pain frames that turn the head left or right when getting hurt from the sides, or clenching teeth when hurt from the front or holding the fire button for a while. The Ouch face from the PC counterpart remains unused in this port.

Unused Audio

Gibbing Sound

There's an unused gibbing sound at offset FDF27C that goes for 7707 samples in length at 8000hz, despite gibbing being removed from this version.
