It’s time for another adventurous Summer Sale! Join us for two whole weeks and lie by an ocean of game premieres and 1000+ deals, gather XP to unlock free games, and participate in summer activities! It’s seriously the neatest one yet.

System Shock 2 is free for the first 48 hours to help us improve the GOG Galaxy client with a stress test giveaway. If you want to help out (and score a freebie), simply download GOG Galaxy, visit your experience page through the client, then claim and download your free game.

We’ll have more and more deals for you every 24 hours as the 2016 Summer Sale marches on – and the deals will stick around until the end — starting with The Witcher 3: Wild Hunt (-50%), Rebel Galaxy (-50%), and Day of the Tentacle Remastered (-33%) as well as bundles including X-Wing and TIE Fighter, D&D Gold Box classics and more. Come, or stay, but do look out for more awesome deals and game premieres!

And this year, they’ve also made a bit of a game out of the sale; you can earn experience points for checking in daily (among other tasks). And those experience points translate into free games:

This is the really cool part – check in every day, participate in activities to collect badges, and buy stuff during the sale to earn XP. As you progress, so will your Summer Sale hero, plus you’ll unlock free games: Spelunky, Gabriel Knight: Sins of the Fathers – 20th Anniversary Edition, and Dreamfall Chapters Season Pass.

Some of the activities are fairly trivial, such as visiting your account security settings (a none-too-subtle indication that GOG are interested in having you enable two-factor authentication on your account, that). Some, like adding certain numbers of games to your wishlist, are a bit more involved…but not overly so.

At present, none of the Ultima games appear to be on sale. The Witcher 3 is on sale for 50% off, and buying it will net you a cool 25,000 experience points…meaning that if you also check off the daily tasks for free points, you should be easily able to nab that copy of Dreamfall Chapters for no additional cost.
