Edit: now it's USD $0.50!
After the original deal for voting in the Golden Joystick Awards, now you no longer need to vote.
Add the pack to your cart, put in the code and it'll be $1 USD.
I must admit I already own Spec Ops: The Line and Sid Meier's Pirates! and I'm guessing the 'mystery game' will be something crappy, but if you don't own the other two (or want to give them away as xmas presents!), then this looks good.
Thanks for the deal!
I got Insecticide as my 3rd.
