Update

Epic Games responded to our request for comment on various events discussed in this article. In regards to Oxygen Not Included being removed from the Epic Games Store, Epic stated that, "Klei has chosen to not participate in the Epic Mega Sale and Oxygen Not Included has been temporarily removed from sale," as they honor the developers choice, but will also honor purchases made at the lower price.

In regards to Hades, they referred us to Supergiant Games most recent comment.

Finally, in regards to Ubisoft games not being available for purchase they pointed us at a statement regarding it being a technical issue with their launcher's integration with uPlay.

Epic has changed how sales display on their storefront now. They have released the following tweet announcing the change:

Original Story Below

The Epic Mega Sale started this morning, and we published a deal article with a selection of titles that readers and users might be interested in, both games already available to play and games still only available for pre-order. One of them was Supergiant Games' Hades, which, as per our article this morning, had a 65% discount at $6.99. It's now $9.99, but, during the writing of this article, the price has changed from $14.99 to $9.99.

Supergiant Games put out an initial statement on their Discord server:

Hey, we wanted to let you know Hades is currently on sale for $14.99 after discounts on the Epic Games store. Folks can pick it up at www.PlayHades.com. We think there's never been a better time to experience our rogue-like dungeon crawler! The game's retail price is now $24.99, up from $19.99 at launch, based on continued improvements and additions we've made so far in Early Access, including: an entire new biome, 7 new fully voiced characters including 4 new bosses, hundreds of new fully voiced narrative events, 10 new enemy types, a new weapon, and dozens of new powers and abilities. All told, we think this new price point reflects the game's current value in Early Access. As we expect to continue in Early Access until sometime next year, it's possible we adjust the price again by the time Early Access is complete. We'll strive to provide plenty of advance notice if that happens. Thank you for your support of this game!

They also answered queries, apologized, and clarified what happened on Twitter:

Now they have just made another announcement on their Discord server again to explain the latest price change:

Hey again everyone. Earlier today, Hades became available at a significant discount as part of the Epic Mega Sale on the Epic Games store. We communicated poorly in the hours that followed, and want to clear things up. The retail price of Hades is now back to $19.99, our original launch price. With the Epic Discount, you can get the game for $10 off that price right now, through to the end of the sale on June 13. After the sale is over, on June 14, we will be raising the game's retail price to $24.99. We had intended to raise the retail price of the game soon, but made the decision rashly as part of the sale -- we didn't provide advance notice to our customers, despite previously stating we would do so. That was our mistake, and we sincerely apologize. To all our players, thank you for your patience and understanding around this.

Meanwhile, our TechRaptor staff started investigating, and we noticed price changes for other games and some other differences with games missing. Metro Exodus was $39.99 this morning, and now it's $34.99. Deep Silver announced the (up to) 25% discount on Twitter:

Oxygen Not Included is no longer available for sale. The game is simply not listed on the store anymore, and even if you have it in your library you can't open the store page anymore. This is similar to how Vampire: The Masquerade - Bloodlines 2 has been removed from the sale by Paradox Interactive, who didn't want to take part in the sale, as we reported earlier.

The Division 2 is also no longer available for sale, neither are other Ubisoft titles like Anno 1800 and Watch_Dogs 2. Epic Games Director of Publishing Strategy Sergey Galyonkin explained the reason to a Russian user on Twitter. Here's a Bing translation: "We have a problem with the link accounts Uplay from the weekend until they removed their games from the sale. I really hope that I will fix it until the end of the sale, but I do not undertake to promise."

We have reached out to Epic Games, Ubisoft, Klei Entertainment, and Deep Silver for comment and will update the article as soon as information becomes available.
