Humble Bundle is releasing a new collection to help support relief efforts during the war in Ukraine. (Disclosure: Humble Bundle is owned by Mashable's publisher, Ziff Davis.)

100% of its proceeds from the gaming company's "Stand with Ukraine" bundle will go toward humanitarian aid for those affected by the Russian invasion. Charities that will receive the donations include Razom for Ukraine, International Rescue Committee, International Medical Corps, and Direct Relief.

The one-week bundle features over 120 pieces of content — from games to RPG books to game dev assets — and is valued at over $2,500. For a donation of $40, you'll get the entire package.

Humble Bundle is a "pay what you want" storefront, so while $40 is the minimum you must donate to receive the full bundle, you can always give more if you're able.

Some highlights in the mix include Back 4 Blood, Metro Exodus, Spyro Reignited Trilogy, Max Payne 3, Sunset Overdrive, Slay the Spire, This War of Mine, and more (all of which can be redeemed via Steam once purchased). Check out the full list here.

At the time of writing, Humble Bundle had raised more than $900,000, with more donations accruing by the minute. The offer runs until March 25.
