The folks over at Humble have unveiled the early unlock game for October's Humble Monthly bundle: Overwatch, which can be unlocked for the one-month subscription price of $12. That's a nice discount from the game's $40 street price, and even cheaper than Blizzard's relatively regular 50 percent off sale. 

Humble Monthly offers up a collection of games each month on a subscription-based system. Anyone who subscribes by October 5 will get a bundle of mystery games, and subscribing now grants immediate access to Overwatch. Last month's bundle included Rise of the Tomb Raider, Sniper Elite 4, Tales of Berseria, Staxel, Battle Chef Brigade, Darksiders II, and several others.
