Get Volume and Grim Dawn on the cheap in the latest Humble Bundle, and help support essential multiple sclerosis services and research

This is a good Humble Bundle.

The latest Humble Bundle is one of the Staff Picks series - one of Humble's employees chooses the games and charitable beneficiary.

Engineer Nick, in his guise as a rad panda avatar, is responsible for this bunch, and has chosen the Multiple Sclerosis Society of Northern California, along with Able Gamers, in the wake of his own diagnosis. You can nominate your own charitable cause, too.

Anyway, this week you can pay what you want for Volume, TIS-100 and Legend of Grimrock 2.

If you beat the average price, which was $3.78 at time of writing, you'll also score Infinifactory, The Secret World and Dungeons 2.

If you cough up $14, you can also grab Grim Dawn, a well-received action RPG built on the same engine as Titan Quest, which regularly expands with free content updates.

All games are PC only this time - no Linux or Mac - and some are available DRM-free. As ever, you choose how money is split between developers, Humble and charity. Go take advantage.
