Green Man Gaming are offering 20,000 copies of Sniper: Ghost Warrior from 1300 GMT January 1st while stocks last - just use voucher code GREEN-MANSS-NIPER at checkout to receive a 100% discount on the title!
This voucher won’t expire at a specific time, but after it has been used 20,000 times it will stop working!
Update: Website is taking a hit. GMG confirm via Twitter that keys are still available but to be patient as they're trying to get the site back up and running.
