Welcome to Boomathon.com. The first ever (that I know of) definitive list of Boomer Shooters to ever exist in one HUGE list.
I'm JRodsLegend and it has become my sole mission in life to play through EVERY Boomer Shooter / Retro Shooter to ever exist and leave my own personal review/comments regarding my experiences.
With that out of the way, here is the link to the list and below is how to navigate it!
It's simple, really:
Just click on Enter The Boomathon
Click the tab you want to see, separated by Released Games, Early Access titles, and Unreleased Games
Check out which games have already been played, the next ones on the list and even the bonus Doom Wads we play from time to time!
Enjoy!
