The Humble Store's Spring Sale is now underway, with discounts of up to 90 percent on more than 4000 games - and 100 percent on one of them. The sci-fi RTS Ashes of the Singularity: Escalation is free for the taking until Sunday.

To claim your free stuff, point yourself here and click the appropriate button. You'll need to sign up for the Humble Newsletter, if you haven't already; with that taken care of you'll be given a Steam key for your efforts. Note that while the game is free to keep forever after you've claimed it, the keys themselves have a relatively short expiry date of May 14, so be sure to activate it right away

In related news, Epic Games is giving away FREE copies of Death Coming, a grim puzzle game in which you kill people, starting today and lasting until May 14th 2020.
