Hi!
I have these Origin keys unredeemed:

Dead Space Origin Key
Burnout Paradise: The Ultimate Box Origin Key
Crysis 2 Maximum Edition Origin Key
Medal of Honor Origin Key
Mirror's Edge Origin Key
Command & Conquer: Red Alert 3 - Uprising Origin Key
Populous Origin Key

** The winner of this "game"(who posts the right answer first) will receive all of these.(i will add him/her on steam)
But it's not so simple, because i only give you these two "words" to help:

BAND + MYTHOLOGICAL CREATURE = ???

You can only write ONE answer(word) in a comment, but you can comment as much as you want.
I'll update the Discussion when there will be a winner.
GOOD LUCK! :D **

UPDATE 1:
OK, looks like you need a hint: I'm thinking about the name of a BAND, which is related to a mythological creature. So it's NOT an artist.

UPDATE 2:
It's over!!...the right answer was "Chimaira". Many people posted "Chimera", but they are two different bands... the winner will now receive the keys.
