They are woven into the game by random spawners, which replace the original weapon/monster types. All of them are heavily based off the originals, with most changing attacks and/or sizes, and all being recolorations (with the majority being by pallette translation). OMGWPNS features 20 extra weapons and 43 new monsters.
It was one of the first ZDoom PWADs to be released to the idgames archive that included DECORATE weapons, and thus requires the ZDoom Community Build or GZDoom to play. OMG Weapons! (and Monsters) (or OMGWPNS) is a weapon and monster modification released by Dean 'deathz0r' Joseph in July 2005. The player fends off a Blood Imp with the Auto-Railgun.
