The Steam Intergalactic Summer Sale is a special set that was made available during the 2018 Summer Sale. The cards initially became available on 14 June 2018, though were not craftable into a badge until the sale began on 21 June 2018.

There are 10 cards in the series, and you can earn three cards per day by enter a tile from the Saliens game that was released alongside the sale. You will also earn a card each time you use your Discovery Queue, up to 3 times per day. You can also earn cards by crafting a badge from any other card set - doing so will give you one card at random in addition to the normal badge crafting rewards. Additionally each $10 spent from buying games will grant you one card.
