Osiris

Osiris is a Doom II episode replacement mod of eight levels, created by Marshal Bostwick and Glen Payne in 1996. The original music was created by Jeremy Doyle.

The first three maps were previously released as I, Anubis in 1995.

It was included in Doomworld's Top 25 Missed Cacowards feature in 2018.

Custom content
The wad comes with a Dehacked file (osiris.deh) which makes cosmetic changes to several of the weapons, with the maximum ammo capacity of the rocket launcher&mdash;now a flame-thrower&mdash;equaling 100 (200 with the backpack), as well as new cheat codes. It also applies changes to the monsters, namely:


 * The shotgun guy is now a blue marine with 40 hit points.
 * The imp now represents Anubis and fires cacodemon fireballs. It has 50 hit points.
 * The demon and spectre wield scythes.
 * The lost soul is now a bat which has 70 hit points.
 * The arachnotron now has 750 hit points and is a plasma-firing pharaoh.
 * Several decorative items, as well as the spiderdemon, are now sound effects.
