note:to bind the headlight key in android(DELTA-TOUCH)you must use console command and custom button. example:"bind kp_end(kp1) toggle headlight_toggler" *you don't need to type "(kp1)"
this is for "doom 3 resurrection of evil",put this pk4 file into d3xp or dexp folder.
Headlight can go wrong when using The Artifact.
