The bundle, which launched today and expires on November 22nd, is fittingly titled the Humble Unreal Engine Bundle and  features a variety of great games as outlined below.

Pay $1 or more for Killing Floor + "Community Weapon Pack" 1-3 & "Chickenator" DLC, Dangerous Golf, and Shadow Complex Remastered. You'll also receive a coupon for 10% off Humble Monthly for new subscribers.

Pay more than the average price and you’ll also get The Vanishing of Ethan Carter, ADR1FT, and The Mean Greens - Plastic Warfare.

Pay $10 or more for all of that plus The Culling (Early Access).

Pay $1 or more. Normally, the total cost for these games is as much as $119. Over at Humble Bundle, though, you choose the price of $1 or more!

Redeem on Steam. All of the games in this bundle are available on Steam for Windows; some are also available for Mac and Linux. Pay $1 or more to access Steam keys. Please check out the full system requirements here prior to purchasing.

Support charity. Choose where the money goes – between the developers, Girls Make Games, future recipients of Unreal Dev Grants, and, if you'd like, a charity of your choice via the Paypal Giving Fund. If you like the bundle or like what Humble Bundle does, you can leave them a Humble Tip too!
