this is a concept teaser for a fan sequel to Doom 2 (cuz Doom 3 was a prequel and Doom (2016) rebooted the whole series) that take's place in the final Hell invasion on Earth where they go for an all out attack and of course DoomGuy is there and has to stop it
i just did some stuff in the drawing parts, some new form of Spider-Mastermind which will probably be a boss, and the BFG 9000 (the best gun in every Doom game except for Doom 64 which has the Unmaker which when fully upgraded is more powerful) pointed at it
