Alien Isolation on nightmare mode. You like that in-game map don't ya? Too bad that's gone now. Low on ammo and supplies? Well, heres a room full of empty loot containers. Who needs a HUD? Better not breathe too loud, or an unstoppable killing machine will pull your anus out through your nose. That flamethrower that works so well? Yeah, it takes about 80% of your fuel to scare off the Xeno [b][i]once.[/i][/b] Not impossible, but very intense.
