The current Humble Monthly just became a much better deal for Linux gamers with two brand new early unlock titles.
Previously, it only had Overwatch (which is playable with Wine + DXVK) although there were some issues recently with Linux gamers being banned and then unbanned. Nice to know Blizzard was good enough to overturn the bans, but still a little risky.
Thankfully, Humble just added Dungeons 3 and Hidden Folks two native Linux games and they're both really quite good. Both games are wildly different and two titles I particularly enjoyed playing, so they're worth picking up.
Considering you also get access to the Humble Trove which has plenty of native Linux DRM free games and a 10% discount in the store, this month is looking like a reasonable deal. Check them out in the Humble Monthly.
They do also still have the The Humble One Special Day Bundle, which has Surgeon Simulator: Anniversary Edition and OlliOlli2: Welcome to Olliwood which have native Linux versions (some of the other games are known to work with Steam Play).
