For those looking for some extra games to pass the time during the hot summer months, the new Humble Monthly once again has some Linux offerings.
With the early unlocks, you will be able to get access to The Escapists 2 right away (along with two games that aren't on Linux).
On top of that, you also get access to the Humble Trove, which has a ton of DRM free games you can download and keep. They've just boosted the games included once again, to include Amnesia: A Machine for Pigs in addition to 30+ other Linux titles.
For $12, it's worth it even just for the titles in the Trove collection and you're able to cancel any time you wish.
Take a look at the Humble Monthly if you're interested.
