Left for dead 2, or Rock of Ages?

So, it's time to me to do a new giveaway. This time I'm gotta create it private to raise chances, so you know what will happen: one puzzle will pop up here eventually. So, please decide wich one I'll give away:

• Left for Dead 2
• Rock of Ages

In the meantime, enjoy this

EDIT: Left for Dead 2 it is then, I'll prepare the giveaway for the upcoming week!
