[H] Multiwinia (Steam), 50% off on DEFCON coupon [W] Details inside (Steam)

I have a copy of Multiwinia and I am looking for some coal in return (minimum 3, pref. more). I can also give away a coupon that will get you 50% off on DEFCON in the beginning of next year. I can give this together for a better deal or separately for something like coal.

If you are generous, get me a cheap game or Portal 2. Cheap games may be:

• Space Pirates and Zombies
• Plants vs. Zombies
• Peggle Deluxe or Nights or Complete
• Half-Life 2: Episode Two (less preference compared to all others)
• Any game that you have lying around/would like to trade (but ask me first)
