Doom 2016 is the 2016 first-person shooter reboot developed by id Software, following the Doom Slayer through Mars and Hell. Kadingir Sanctum is one of its Hell levels, where demonic voices and announcements build dread between combat encounters. The he is here line comes from that atmosphere of warnings directed at the Slayer's arrival. Clipped from gameplay, the moment spread through gaming soundboards and edit communities because its meaning works outside the game, turning any ordinary entrance into a sign that a feared presence has just arrived.
