Persona 5 Royal Mod Lets You Play Doom In-Game

Fans have gotten id Software's classic shooter Doom playable within Atlus' hit JRPG, Persona 5 Royal. The iconic first-person shooter game is one of id Software's most beloved titles, having been ported to several different video game systems over the past three decades.

Morgana actually has some unique flavor text upon purchasing the game, where he acknowledges how Doom was one of the most influential FPS games in the '90s. The player can then boot the game up in the hideout, which is shown as a red cartridge that is placed in Joker's console, much like how Doom had a red SNES cart when it was ported to the system.

This port is based on the shareware version of the game, meaning the mod only covers the first level of Doom, «Knee-Deep in the Dead.» Both the in-game tutorial and Morgana acknowledge this is the shareware version, and that if players manage to beat it, they can purchase the full version of the game through the in-game secondhand shop (though the Doom.wad file must be in the mod's Doomsona folder). Faz then demonstrates how the game
