Dab's Mod v3.2.1
Bodies no longer vanish. With Bodies on, kept bodies disappeared once you looked away from them: the game's own corpse reaper, sized for the N64, fired when the store that holds blood decals ran out and faded every off-screen body. Kept bodies are exempt now and the store grows with the Bodies setting, so the blood keeps appearing too.
Light glares stop drawing through the gun. A glare behind the weapon used to paint over it, which read as a translucent gun. It is now hidden by the gun, and in third person by your own body.
XBLA meshes on a key. F6 (Mod.XblaMeshKey, bindable in Dab's Mod Options) turns the Xbox 360 models on and off in the level, the way F8 does texture packs.
Everything from v3.2.0 (stock defaults on a fresh install, the Settings Preset) is included.
