This website is designed to introduce people to Doom and its many games.
The main protagonist of the Doom franchise is the character with many names.
Some people refer to him as the Doom Guy,
some call him the Doom Slayer.
The main premise of this series is our protagonist killing demons who have invaded
Earth in the future.
This franchise can be split into 3 types on the basis of its... eras, I'd say.
Though the mobile doom games were developed in almost all eras.
Here's a wiki page if you need more info :D.
