The Humble Codemasters Bundle is still running, and more games have been added to sweeten the deal. The Bundle is available through December 8, 2015, and includes a number of popular games available for the PC. Game codes are redeemable on Steam, and money goes to two charitable causes: Prince’s Trust and GamesAid.

As with all Humble Bundles, the Codemasters Bundle is a pay-what-you-want format with more games unlocked at higher pay tiers. Paying any amount will get customers: GRID 2, DiRT Showdown, Overlord, Operation Flashpoint Complete, Hospital Tycoon, and Colin McRae Rally.

Those who pay more than the average ($5.65 as of this publishing) will also get: GRID Autosport, Overlord II, Overlord Raising Hell Expansion, GRID 2 Spa-Franchorchamps Track Pack, GRID Autosport Drag Pack, Toybox Turbos, GRID, and Rise of the Argonauts.

Those who pay at least $15 will also get: Grid Autosport Season Pass, DiRT 3 Complete Edition, and GRID 2: All In DLC Pack. Coupons included in the bundle are for 25% off Overlord: Fellowship of Evil and 25% off DiRT Rally. So far, nearly $700,000 has been raised through this bundle.
