Humble Bundle has launched a new "Arc System Works EVO Collection" bundle that includes popular fighting games and directs proceeds to support the Raiden Science Foundation and its Fight4Rare initiative, which aims to advance research for rare diseases.

The bundle, available until July 17, contains up to 16 items, including games and DLC coupons, with prices starting at $5 for a 10-item package. Higher tiers include more content, with the most comprehensive 16-item collection available for $20.

Notable titles in the bundle include Guilty Gear -Strive-, BlazBlue: Central Fiction, Guilty Gear XX Accent Core Plus R, BlazBlue Cross Tag Battle Special Edition, and Guilty Gear Xrd REV 2 Deluxe Edition. The higher tiers also offer discounts on multiple Guilty Gear -Strive- season passes.

The Raiden Science Foundation was established by Tommy and Linda Pham in honor of their son, Raiden, who was diagnosed with UBA5 Disorder, an ultra-rare genetic condition. The foundation focuses on raising awareness and funding research for rare diseases. The Fight4Rare initiative, inspired by Mortal Kombat and Raiden's name, seeks to engage the gaming community in supporting these causes.

Tommy Pham shared a personal connection to Guilty Gear -Strive-, noting that the game helped him through a difficult period around his son's diagnosis. The character Ky Kiske, associated with hope and lightning, also holds significance in relation to Raiden. The bundle's inclusion of these games is seen as a meaningful way to support the foundation's mission.

The initiative has also received support from figures within the fighting game community, such as Mark Julio (MarkMan), who has been instrumental in connecting the Phams with resources and fostering community involvement. This collaboration highlights the broader impact of the fighting game community in supporting charitable causes.
