As the weather is starting to warm up and the big game releases are finally on their way this March, there are still plenty of cheap games available if you're looking to fill up your backlog - case in point, Steam is offering the chance to play both Tropico 5 and Killing Floor for free this weekend before you give them a buy.

Steam is hosting a Free Weekend for users of the service to play both Tropico 5 and Killing Floor free this weekend, with both games fully playable now through Sunday, March 22nd, 2015 at 1pm PST.

If you end up enjoying both titles and want to keep playing past the free weekend, both will be available at discounts of 75% off until Monday, March 22nd, 2015 at 10am PST. Tropico 5 will be available at a discounted price of $10, alongside a special two-pack for $17.49 or a four-pack for $30 if you want to share the love with some friends.

Killing Floor will be available at a discounted rate of just $5, and like Tropico 5, will also offer multi-packs with a six-pack of the game for $24.98 that you can share with friends - the game's DLC is also on sale, with prices for the DLC ranging in price from around $1.24 to $1.99 each.
