Steam has numerous sales but it doesn't exactly have a Black Friday one. It has the stand-in Autumn sale, whose date has been leaked long ago. Not many planned discounts are known though, barring the sales on Destiny 2's various options.
Steam's Autumn Sale is set to start on 26 November 2019 which is a few days before the Black Friday but the sale is too close to the actual event not to be connected, much like in previous years. The sale will last for a week, until 6 December 2019 so if one is looking to reinforce their library, they might need to be mindful about the inevitable shopping spree on the actual Black Friday which will occur three days after Steam's sale commences.
Considering the Holiday Season is merely a month away, everyone's wallets should brace for the double impact in the span of roughly 30 days. While it's unknown what Valve will discount and how much the players can save on their favourite titles yet, Bungie spilt the beans and revealed their entry.
Destiny 2 is free to play on Steam but there are a few options the players can purchase. Forsaken and Shadowkeep expansions are going to have 40 per cent lower prices for the duration of Autumn Sale. This should translate to $21 / €21 / £18 for Shadowkeep and $15 / €15 / £12 in the case of Forsaken. It's $36 / €36 / £30 for the full package.
Shadowkeep Deluxe Edition will be discounted by 25 per cent but keep in mind that this pack includes four season passes and some in-game cosmetics but does not have Forsaken with it.
Considering the nature of Steam sales, it's hard to imagine any noteworthy title won't be discounted so keep an eye out on your wishlists. Also, keep the other eye out for your wallet's well being. Lord Gaben has a tendency of murdering them from time to time.
