Dead Space 2 Hardcore mode unlockable captured, amazing
Someone's grabbed video of a weapon you get as a special unlock if you're daft enough to brave Dead Space 2's Hardcore mode. You only get access to the new level of difficulty after beating the game, and you're then challenged to best single-player on ultra-hard with only three saves in total.
Maybe this'll help you push through the pain, though. Warning: obviously this is a massive spoiler.
