Steam Summer Sale 2014

The Steam Summer Sale 2014 was a Steam event. It featured a Steam Trading Cards system, which could be collected to craft badges and earn rewards.

Rewards
In addition to standard Steam community rewards (emoticons, profile backgrounds, etc), Steam Summer Adventure badges crafted during this event will also grant 1 random gift. Crafting a foil Steam Summer Adventure Badge will grant 5 random gifts.

Note that the gift earned may not be a Dota 2 gift, and in fact a gift for one of the other 10 participating games.
