October's Humble Monthly is available, and it's a doozy. If you subscribe between now and October 5, you'll get immediate access to Overwatch, Blizzard's enormously popular hero shooter that normally retails for $40. A one-month subscription only costs $12, and Overwatch is yours to keep and play forever, even if you unsubscribe. On October 5, a number of other games will be revealed that you'll also get to keep. This is an incredible deal for anyone who plays on PC and hasn't picked up Overwatch yet.

If you keep your Humble Monthly subscription going, you'll also get free Overwatch loot boxes in November and December, in addition to those months' free games. Loot boxes contain cosmetic items like skins, emotes, and voice lines for the heroes.

Most of the games you receive come in the form of Steam codes. For an idea of what kinds of games you can expect to receive in September in addition to Overwatch, previous months' offerings have included Rise of the Tomb Raider, Conan Exiles, Little Nightmares, Sniper Elite 4, Darksiders II: Deathinitive Edition, and Battle Chef Brigade. Even though a subscription only costs $12 per month, you generally get around $200 worth of games each month.

Subscribing to Humble Monthly gets you additional benefits beyond free mystery games. You also get access to the Humble Trove, a collection of over 60 games you can download and play for as long as you have an active subscription. Another benefit is that you get 10% off Humble Store purchases. And 5% of your subscription fee goes to charity.

So if you're a PC gamer who wants one of the best, most reliable deals in gaming, consider signing up.
