Indie studio RedBedlam has released a trailer for their multiple generation genre-hopping first person shooter called ‘Bedlam,’ a game based on a sci-fi novel of the same name.

‘Bedlam’ is an FPS on Steam Early Access that throws players into the shoes of Heather Quinn, an underpaid programmer at a medical scanning developer called Neruosphere. One rainy morning at work, Quinn volunteers as a test candidate for Neruosphere’s newest brain scanning technology. However, immediately upon initiating the test, she suddenly finds herself transported into the world of Starfire, an old school FPS that she used to play as a teenager in the nineties. In search for a way out, Quinn ventures only to find herself deep within a realm of interconnected game worlds documenting the evolution of the FPS genre and videogames in general.

The main draw of ‘Bedlam’ is its genre-hopping FPS gameplay. From what is shown in game’s new the trailer, Quinn will be venturing through a multitude of different gaming generations as the game progresses. Be it from pixelated ‘Pacman’-esque levels to ‘Quake’ and ‘Elder Scrolls’ inspired levels with FPS shootouts; ‘Bedlam’ seems to be throwing players into a crash course in gaming history with its interconnected game worlds.

As mentioned, ‘Bedlam’ is adapted from a sci-fi novel written by cult Scottish author Christopher Brookmyre. In the original, the main protagonist was a scientist named Ross Baker. However, for the game adaptation, it was decided to change the protagonist to a female lead – who is a gamer and all around sci-fi fan – to offer a new perspective upon ‘Bedlam’s’ “gameverse.” Baker will now be featured prominently as Quinn’s colleague.

Having steadily received updates since it hit Steam Early Access in August, ‘Bedlam’ recently received yet another update that expands the game to 15 levels and around three hours of gameplay. In addition, the update also put in two of the game’s classic arcade levels called “Chili Chomper” and “Guano Attack,” each based on ‘Pacman’ and ‘Space Invaders’ respectively.

“I’m really excited for people to experience the new content we’ve created for Bedlam,” said Nick Witcher, Marketing Director at RedBedlam. “I’m incredibly proud of our work on Chilli Chomper, and as expected Pac Man is absolutely thrilling and pretty scary as an FPS.”

‘Bedlam’ is now available on Steam Early Access for PC and Mac.
