Deals on Steam aren't limited to the quarterly mega-sales Valve puts on (though those are nice, too). Each Monday the digital game retailer puts up a new set of PC game deals that last a full week. This week's batch is up, and it contains some great titles available at low prices. Let's see what discounts are available between now and August 27.

All told, 549 games are on sale this week, so there's a good chance you can find something you're interested in playing. Among the standouts is Life is Strange: Before the Storm, which is 60% off, bringing it down to $7. It takes place three years before the original game and focuses on Chloe. Ryse: Son of Rome, a melee-centered action game that tells the story of a Roman soldier seeking revenge against his enemies, is on sale for just $4.

Puzzle platformer fans can pick up The Swapper for $3. You play as an astronaut trying to navigate difficult terrain on a faraway planet. To get from point A to point B, you have to use a device that clones your body. All of the clones also follow your control inputs, making for some fun, mind-bending puzzles.

If you're open to a psychological horror adventure game that's displayed in a big-pixel art style, you can pick up The Last Door: Collector's Edition for $5; it contains four episodes of Victorian terror. And if the idea of surviving the zombie apocalypse appeals to you, you might want to grab How to Survive: Storm Warning Edition while it's on sale for just $2. It comes with the core game, plus six pieces of DLC.
