ARK: Survival Evolved is the latest subscription incentive for Humble's monthly grab bag.
Subscribe to Humble Monthly before March 4 and you'll instantly receive a copy of ARK: Survival Evolved, which goes for $30 on Steam (although it's currently on sale).
Since you can cancel your subscription at any time, and you get to keep your games forever anyway, this seems like a pretty cheap way to get in on the dinosaur survival action.
In case you missed this whole thing, Humble Monthly is a $12 subscription service that delivers a stack of games every month. The gimmick is that you don't know in advances what the games will be.
In general, it seems to be a mix of a few triple-A titles and well-received indies, usually a few months old - making it an interesting prospect for budget-wise gamers who wait for lower prices down the track rather than picking up new releases.
Most of the games seem pretty good so far; last month, subscribers received Alien: Isolation, Volume, Dropsy, Broken Age, Titan Souls and Penarium.
Keen? Take a gander at Humble Monthly.
