It probably goes without saying that Doom RPG isn't the most well-known entry in the Doom series. Released for mobile devices/phones back in 2005, it was developed by Fountainhead Entertainment and incorporated RPG elements like turn-based combat, status effects, and levelling, as well as boasting a much greater emphasis on story. Nevertheless, despite being one of the series's stranger installments, it got some fairly decent reviews back in the day and was later given an unofficial port to modern PCs in 2022.
Now, GEC.Inc, the team behind that previous port, has announced on Twitter that it has also successfully reverse-engineered and ported the game's sequel Doom II RPG to modern PCs as well. This sequel was originally released back in 2010 for the iPhone and iPod Touch and took place one year after the first game's events. Much like its predecessor, it was also fairly well-reviewed, with both Touch Arcade and IGN counted among its fans.
In it, you play as one of three characters, which includes the scientist Riley O'Connor, the marine commander Kira Morgan, and Stan Blazkowicz, a distant relative of Wolfenstein 3D's protagonist B.J. Blazkowicz. Each of these characters belongs to a special group who have been sent to investigate a monster invasion on the moon's earth, which (surprise, surprise) turns out to be infernal in nature.
Like the original port from 2022, this most recent project features no copyrighted assets and requires the game's files in order to work. It also allows you to play the game with Xbox, PlayStation, and most generic brands of USB controllers. You can watch a video of the demo below. And you can find more information on the Doomworld forums, such as the keyboard controls, cheats, and instructions on how to get it all up and running.
