Couldn't find an already existing thread, so I made this one. The first level of Doom 4's available to download as a free demo on Steam. I played it last night, and enjoyed it so much I jumped right back in on a harder difficulty. With just the weak starter energy pistol. Which I love. Nothing like moving around, taking careful aim, and turning a baddie's head into a spurting fountain of blood. Also, the glory kills are awesome. I ripped a demon's leg off and shoved it, boot-first, through the demon's face. It was glorious. I did have some trouble getting it to work, but that's a several-year-old laptop with out of date video drivers for you.
