I'm yet to finish Doom64, time to change that! Hopefully I'll get the last 6 achievements on the way.
Level 28, I had not found any secret levels that had demon keys, so had to do this the hard way. It took me a bit to work out to circle strafe, do some infighting and kill those freaking pain elementals! Running at high speed was the best with the boss.
