Hopefully I'm not alone here in thinking the new Doom is absolutely brilliant? It's been such a long time since I played an FPS that wasn't all about hiding behind a wall and poking out every so often. Just good old "these guns and those demons have an appointment".
Nightmare mode is absolutely kicking my arse though. Says a lot when even the basic Imps can smoke you in one hit with a charged attack... how someone has managed to complete Ultra Nightmare is just beyond me!
