We love to take advantage of the video game deals over at Steam, even more so when they give us a chance to try before we buy. This weekend, they have a few good promotions worth checking out if you're looking to put in some quality time with your PC and maybe a friend or two. Here's a look at what's on sale until Monday at 1pm EST:Steam games routinely go on sale every so often but, if you're not interested in waiting for a the big summer sale, you can get in your hours of Portal 2 and Worms Revolution early! As an added bonus, you can play Worms Revolution absolutely free until Sunday at 1pm EST. If you're not quite sure if you'll play it more than a few times, try it out and make a decision. Don't you wish you could try all games before you buy?
