Before you'll ask questions, I'll give you some important points.
-I'm making this megawad like if it's an INDIE GAME, sometimes, I can't use assets that haven't made by me!
-The campaign will be based on the Hotline Miami universe, you'll see some references.
-I'm not sure yet if I gonna make this megawad a show, even if the demo will be complete.
-This megawad targets on the hardcore gamers, that's means that you'll get for the most unfair moments even for the official campaign, so I know what you're thinking but I have nothing against speedrunners, you can of course but I prefer that you'll play on the most easy skill! Not hardest which I don't recommend, exept if you folks are suicidal!
-Brutal DOOM? Well, you can run with it but(t) you don't have personality! And I'm serious! (Don't worry, I have nothing against Brutal DOOM)
Time for questions while I'm working on the official campaign and the gameplay core in the same time, and ah! My game design studying in school! I'm open for your questions until the december!
