I’m about halfway through Plutonia now, and I think I can honestly it’s a fantastic WAD. Sure it’s hard, but the maps are all well designed, and the traps are clever and there’s always a way to get through a fight, and you’re supplied with plenty of shotgun shells, and rockets which help a lot of fights. I’ll probably do TNT after just to say I’ve done it, even though I’m not looking forward to it because of the maps being long and boring slogs.
