Like most games, you get some cool stuff for completing Dead Space 2. Complete the game on its "hardcore" difficulty, though, and you'll get something better than cool.
You'll get a foam finger. You know, like the "#1" things you get at sports games. Only this one kills bad guys, and goes "pew pew pew" while you're doing it.
If that sounds ridiculous, the video above will show that it's...well, ridiculous.
Dead Space 2 was released earlier this week on PC, Xbox 360 and PS3. Mike liked it a lot. I'm playing it right now, and I like it a lot, too.
