The annual Steam Summer Sale has begun with ongoing sales for the rest of the month from June 19 to June 30.
Much like Steam's winter festivities, you can also take part in the Summer Adventure. "Offered for free, the Summer Adventure offers the chance to earn in-game items, community rewards, and even free games by collecting Summer Adventure Trading Cards."
You'll want to check back frequently, since the best deals come in the Flash Sales and Daily Deals, but the event is kicking off with the deep discounts of 75-80% off big titles like The Witcher 2 (currently $4), Far Cry 3 ($7.50), and XCOM Enemy Unknown ($7.50).
Any deals you're leaping on now, or any games you've been waiting all summer for this sale to pick up? Let us know in the comments below!
