## Summary
Humble Bundle has launched its 15th Anniversary Sci-Fi Exposure Bundle, an eight-game collection priced at $25 USD with a claimed retail value of up to $375 USD. The bundle includes notable titles such as RoboCop: Rogue City Collection, Ghostrunner and Ghostrunner 2, the remastered Crysis trilogy, Marathon, and Xenonauts 2. For Linux gamers, the significant detail is that all titles are Windows builds with no native Linux ports; compatibility depends entirely on Valve's Proton translation layer.

Most bundle titles carry Steam Deck ratings: Ghostrunner 2, Crysis 2 Remastered, and Crysis 3 Remastered are Verified, while RoboCop: Rogue City Collection, the original Ghostrunner, Crysis Remastered, and Xenonauts 2 are rated Playable. Marathon has no Steam Deck rating. The bundle runs on a pay-what-you-want model with proceeds supporting Charity: water, and Steam keys must be redeemed before May 11, 2027.

## Proton compatibility and Steam Deck ratings breakdown
- **Proton dependency:** All eight titles are Windows-only builds with no native Linux versions, requiring Proton for SteamOS and desktop Linux execution.
- **Verified titles:** Ghostrunner 2, Crysis 2 Remastered, and Crysis 3 Remastered hold Steam Deck Verified status, indicating full controller support and no manual configuration needed on Steam Deck.
- **Playable titles:** RoboCop: Rogue City Collection, Ghostrunner, Crysis Remastered, and Xenonauts 2 are rated Playable, meaning they function on Steam Deck but may require minor manual adjustments or have small interface issues.
- **Unrated title:** Marathon, a first-person shooter making its bundle debut, carries no Steam Deck compatibility rating, leaving Linux performance uncertain.
- **Redemption deadline:** Purchased Steam keys must be activated before May 11, 2027, creating a time-bound obligation for buyers.

## Why it matters
This bundle illustrates the continuing reliance of commercial Linux gaming on Proton rather than native ports, a trend that reduces incentive for developers to maintain Linux builds while expanding game availability through Valve's compatibility layer. For Steam Deck owners, the Verified and Playable ratings provide practical guidance, though desktop Linux users without Deck hardware may encounter varying results due to differences in Gamescope compositor integration and controller handling.
