Humble’s Arc System Works Bundle Packs 11 Fighters and One Cause

Humble’s Arc System Works: Evo Collection Bundle runs through July 17 and packs 11 fighting games into three price tiers: $5, $10, and $20. Every purchase also routes a cut to the Raiden Science Foundation, a parent-run nonprofit developing a treatment for an ultra-rare genetic condition that, per IGN, affects fewer than 100 known children worldwide.

The bundle arrives in lockstep with Evo 2026, the fighting game community’s biggest annual tournament, which IGN reports ran in Las Vegas June 26-28. Mark Julio (MarkMan), the Director of Global Business Development at Evo, helped connect the foundation to the wider fighting game community, per IGN. The tournament, the bundle, and the charity push all hit the same week.

The Three Tiers, From $5 to $20

The structure is a standard Humble tier ladder, with each higher tier unlocking everything below it. Every game in the bundle arrives as a standalone Steam key.

Tier 2 and Tier 3 both add crossover-friendly titles. The middle tier rounds out the roster with one all-franchise crossover brawler and two distinct fighters. The top tier brings the latest mainline Guilty Gear, plus one BlazBlue mainline and one Under Night In-Birth sequel. The $20 tier is the only one with a dedicated Guilty Gear -STRIVE- install.

IGN pegs the combined retail value of the bundle at $340. STRIVE alone lists at $59.99 on Humble’s own product page. The $5 tier nets outsized value on its own, with the full tier-by-tier game and coupon breakdown laid out on the bundle’s checkout page.

The Family That Turned a Bundle Into a Mission

The Raiden Science Foundation is small, lean, and purpose-built. Tommy and Linda Pham launched it in November 2021 after their son Raiden was diagnosed with UBA5 Disorder, an ultra-rare genetic condition that, per IGN, affects fewer than 100 known children worldwide and leaves him unable to sit, walk, talk, or use his limbs.

RSF has since partnered with UMass Chan Medical School and St. Jude Children’s Research Hospital, and is now working to raise $3 million for a treatment pathway, per IGN. Its gaming-led fundraising runs through Fight4Rare, an initiative that began as Kombat4Rare. The foundation’s published mission statement and active treatment pipeline walks through what the $3 million funds in practice.

Pham’s connection to Guilty Gear predates the bundle’s launch. Guilty Gear -STRIVE- released just months before Raiden’s diagnosis, and Pham told IGN the game helped him get through one of his darkest chapters. STRIVE features a character, Ky Kiske, whose themes center on hope and lightning, a link Pham called “pretty amazing” given Raiden’s mythological namesake. Tommy and Linda Pham named their son after the Mortal Kombat character Raiden, the God of Thunder who commands lightning.

For me, Mark represents what makes the FGC so special. He saw a family trying to save their son and chose to stand beside them. Through his support, and the support of the broader FGC, what began as one family’s fight became a community’s fight. That support continues to fuel everything we do today.

That quote is from Pham, addressing his relationship with Mark Julio (MarkMan), the Director of Global Business Development at Evo (per IGN). The foundation’s Fight4Rare arm now sits inside the same fighting game community Evo serves. Buyers at any tier route their purchase through that community to RSF.

Why This Drops in the Middle of Evo Week

Evo 2026 ran in Las Vegas June 26-28, per IGN. The bundle’s launch tracks that window. Humble has paired charity bundles with Evo before, but this time the foundation in the byline is one founded by a fighting game family. Pham’s Fight4Rare initiative was built for this community, and the Fight4Rare community fundraising page lists partner events like Evo 2026. Both gaming events are pushing the same $3 million RSF treatment goal at once.

STRIVE was the title Pham reached for during his son’s diagnosis, per IGN. The bundle’s top tier puts that exact game on top. MarkMan, who supported Pham from the start, joined the foundation at Evo 2026 in person. Buyers who don’t attend Evo can still route money to RSF through Humble.

Every Game Runs on a Steam Deck, With Two Caveats

Steam Deck HQ tested each game on Steam Deck and rated them all playable. Two of those 11 entries carry an “Unsupported” tag.

At the $20 tier, Guilty Gear -STRIVE- and BlazBlue CentralFiction are both Playable. Under Night In-Birth II Sys:Celes is marked Unsupported, though Steam Deck HQ reports it working in practice. The $10 tier’s Cross Tag Battle is Playable; Guilty Gear Xrd REV 2 Deluxe Edition and Arcana Heart 3 are Verified. All 11 keys are Steam keys, not Epic or GOG, so they activate in one place.

Three of the $5 tier’s five games carry solid verdicts. Melty Blood Actress Again Current Code and Guilty Gear itself are Playable. Guilty Gear XX Accent Core Plus R is Verified. KILL la KILL -IF and Chaos Code -New Sign of Catastrophe- are marked Unsupported; Steam Deck HQ reports Chaos Code working in practice.

The Steam Deck caveat is mostly cosmetic but worth flagging. Unsupported doesn’t mean unplayable, but Steam won’t display a green checkmark on those games. Steam Deck HQ’s overall verdict: “Every single game here is playable on the Steam Deck, and performs wonderfully.” Verified and Playable ratings display the green check without manual tuning. The three Unsupported flags (two of which Steam Deck HQ reports as working in practice) are the only blemishes.

The list below shows each game’s Steam Deck rating as published by Steam Deck HQ.

• Guilty Gear -STRIVE- ($20): Playable
• BlazBlue CentralFiction ($20): Playable
• Under Night In-Birth II Sys:Celes ($20): Unsupported, but reported working
• BlazBlue Cross Tag Battle Special Edition ($10): Playable
• Guilty Gear Xrd REV 2 Deluxe Edition ($10): Verified
• Arcana Heart 3 LOVEMAX SIXSTARS!!!!!! XTEND ($10): Verified
• Melty Blood Actress Again Current Code ($5): Playable
• KILL la KILL -IF ($5): Unsupported
• Chaos Code -New Sign of Catastrophe- ($5): Unsupported, but reported working
• Guilty Gear XX Accent Core Plus R ($5): Verified
• GUILTY GEAR ($5): Playable

Two Dates You Can’t Confuse

There are two deadlines, and they live a year apart. Per gg.deals, the keys expire on July 17, 2027. Indie Game Bundles lists the bundle itself closing on July 17, 2026. Once the sale ends, buyers still have until July 17, 2027 to redeem their keys.

Both deadlines land on the same calendar day, a year apart. That gap is built into most Humble bundles, not specific to this one. After July 17, 2027, any unredeemed keys lapse for good.

How STRIVE Season Pass Coupons Work

A first reading of the bundle page can mislead buyers. Each tier does not include the season passes themselves, just discount coupons. The 10-percent-off coupons cover all five Guilty Gear -STRIVE- Season Passes, redeemable on the Humble Store per the bundle’s own page.

That’s a separate transaction from the bundle itself, and it carries the usual Humble Store rules. The coupons don’t include the games; they discount the season passes only. STRIVE’s base game lands at the $20 tier as a Steam key, with the coupons sitting alongside.

IGN’s tier breakdown lists 10-percent-off coupons for STRIVE Season Passes 1-5, not the season passes themselves. The coupons apply to Humble Store purchases of the DLC. Buyers who already own STRIVE on Steam can use the coupons to add season passes without re-buying the base game.

What is the Raiden Science Foundation?

The Raiden Science Foundation is a nonprofit founded by Tommy and Linda Pham in November 2021 after their son Raiden was diagnosed with UBA5 Disorder, an ultra-rare genetic condition that IGN reports affects fewer than 100 known children worldwide. It has partnered with UMass Chan Medical School and St. Jude Children’s Research Hospital, and per IGN is working to raise $3 million for a treatment pathway after receiving FDA feedback. Fight4Rare is its gaming-led fundraising arm.

Does Guilty Gear -STRIVE- include the season passes or just coupons?

Just the coupons. IGN’s tier breakdown lists 10-percent-off coupons for STRIVE Season Passes 1-5, not the season passes themselves. The base STRIVE game lands at the $20 tier as a Steam key. To buy the season passes, buyers would need to purchase them separately on the Humble Store (using the coupons) or on Steam.

What is Evo 2026 and what does it have to do with the bundle?

Evo 2026 is the largest annual fighting game tournament, and IGN reports it ran in Las Vegas June 26-28. The Humble bundle launched in the same window. Mark Julio (MarkMan), Director of Global Business Development at Evo, helped connect Tommy Pham with the wider fighting game community, per IGN. The bundle’s flagship title, Guilty Gear -STRIVE-, sees ongoing balance patches and DLC tied to the tournament meta.
