GreenManGaming is giving away free Outbreak Steam keys for the next 48 hours or before they run of keys, whichever comes first.
ABOUT THE GAME:
Explore a nightmarish environment, scrounge for supplies, and battle the undead in Outbreak — an online co-op/offline survival horror game. The clock never stops as you attempt to manage an extremely limited inventory with a murderous horde on the hunt. Choose between acquiring additional weapons, healing items, or necessary tools for progression. You have only one life. Make it count!
UPDATE: It seems to be a VIP you have to have bought something at GMG in the past, but it’s not 100% as GMG is very vague and quiet about the VIP section. Please let us know in the comments if you can see the freebie.
HOW TO GET THIS FREE GAME ON STEAM:
Just head over to GreenManGaming’s VIP area an click the REVEAL NOW button to get your voucher, then add the game to your cart and use the voucher to make it free. Once you have your Steam key redeem it in Steam client to register it to your account forever
