If you want to expand across the galaxy, fight extra-terrestrial wars and build massive fleets of starships, Humble has you covered with their new Explore and Expand bundle.

For £7.47, PC gamers can get access to Stellaris, Galactic Civilizations 3 (with several expansions), Sins of a Solar Empire Trinity and more. If you are a space 4x fan, this bundle is for you.

Like all Humble bundles, this Explore and Expand Bundle is designed to support the American Red Cross and a user-selected charity. Purchasers of the bundle can choose where their money goes, be it to Humble, the developers of these bundles games, to charity of any mixture of these options.
