He's a demon and can be killed with weapons against demons, like the soulcube.
>>6515012t. zoomer who didn't lived in the time Doom was launched and relates Doom with Duke Nukem and Wolfenstein because le e-numales from youtube said it to me.
You don't have any fucking idea of what Doom was in 1993, it was a game ported officially to every platform till 2001-2 because every system wanted that fucking game.
Also, it has the most active/longest community in any game ever, and there are more than 300000 .wads + .pkg mods.
Also isn't a Swedish company the one that fucked the whole Wolfenstein franchise with sjw faggotry?
