After looking at the just-released GBA Doom screenshots, here\'s some thoughts collected from my own observations as well as talk in the forums/chatrooms:
- The game seems to have no blood! This pic shows a messed-up Doomguy, but there\'s no blood on his face, he just looks hung over. This shot has green slime coming out of the Baron, which makes sense actually, since the corpse has green entrails. Most tellingly, this picture has what looks to be a slime pool in the background, while the original scene has a blood pool in the same spot.
- No lightmaps? None of the shots seem to have any noticable light levels. This might be a limitation of the engine, or maybe the GBA\'s notoriously dark screen means the game will be dark no matter what. For instance, E1M8 looks fullbright and certainly much brighter than the original level.
- Texture changes. The previously linked E1M8 shots, as well as E2M9 vs. the original E2M9, show pretty heavy retexturing. Some people have mentioned on the forums that they have noticed Doom 2 textures in the shots as well(?!).
- The levels show signs of having their architecture simplified pretty noticably, but this is to be expected and has happened in most of the other console ports.
