Get a Free Steam PC Game Courtesy of Humble Bundle

Humble is most often known for offering bundles of games for low prices, but now it's giving away the Steam version of nation-simulation game Tropico 4 for free. The promotion is good from now until Saturday, September 10, at 10 AM PT.

All you need to do to get your free Steam code is log in or create a Humble account, go to the Tropico 4 page, add it to your cart, and click "Get it for free!" You'll then get redirected to a page where you can click a link that takes you to your Steam code. From there you need to open Steam, click Games, go down to Activate a Product on Steam, and follow the instructions.

Tropico 4 received a score of 7.5/10 in GameSpot's review. Critic Brett Todd said, "While the tweaks to the economy, government, and mission assignments make it a better game than its predecessor, you go over the same old ground too often. Still, these changes make for a marginally better game, and newcomers to city building should find the game very easy to get into, thanks to the mission structure and constant advice."

Humble also currently offers a bundle that brings together a bunch of classic Sierra adventures with some new titles. You can pay what you want for it, but you'll have to meet certain tiers to get all the games.
