Introduction – The Steam Summer Sale Is Live!
The wait is finally over. The Steam Summer Sale 2026 is officially live from June 25 to July 9, 2026, delivering two weeks of massive historical low discounts on thousands of PC games. If you are a strategy fan, this is the ultimate opportunity to clear out your backlog and grab those massive, hundred-hour time sinks without breaking the bank.
Whether you prefer the grand scale of grand strategy, the meticulous optimization of city builders, the tactical tension of turn-based combat, or classic real-time strategy (RTS) adrenaline, sorting through the Steam store page chaos can be overwhelming. To save you time and money, I have combed through the discounts to find the absolute best strategy game deals available right now, with games ranging from deeply discounted AAA blockbusters to hidden indie gems. Here are the top 20 strategy game deals you cannot afford to miss during the 2026 Steam Summer Sale.
I have played all these games, so this entire article is based on my real experience and expertise in covering these titles, and this article doesn’t use any AI.
20 – Darkest Dungeon
If there’s a game out there that revitalized the interests of gamers all over the world for the work of my favorite horror writer, H.P. Lovecraft, it was Darkest Dungeon. It took the themes, inspirations, and despair of the characters of his short stories and built a game around them, with a difficulty curve to match the insurmountable odds that olden creatures and civilizations from aeons past are supposed to represent, creating a perfect blend of thematic and gameplay consistency that strategy games don’t always deliver. If you never played Darkest Dungeon, you’re missing out on one of the best turn-based strategy games ever made, and be prepared to put at least 30 to 40 hours before you get through one campaign. This is a tough nut to crack, but one you’ll be engrossed by from the first encounter with bandits to the last, against entities that are better left undescribed.
19 – Halo Wars: Definitive Edition
I’m not going to beat around the bush and pretend that Halo Wars: Definitive Edition is the deepest and most complex strategy game ever made. It isn’t. In fact, it was built for console first, and it’s very simple, but I’ll be damned if it isn’t as fun and bombastic, and has a great singleplayer campaign. If you love Halo, you owe it to yourself to play Halo Wars. I’m currently doing another playthrough of the campaign. It’s a perfect game to pick up, move cool units around for a bit, do some firefights, beat a mission, and go back to your day.
18 – Xenonauts 2
On the opposite end of the complexity spectrum, we find Xenonauts 2. Just out of Early Access, this spiritual successor to the 90s UFO: Enemy Unknown cemented itself as the best galactic threat repellent simulator by bringing back all the complexity the XCOM reboot of 2012 removed. Xenonauts 2 looks at its inspiration and brings it to 2026 by expanding on the strategic elements of the campaign, adding a fighter-combat mini-game, and making the turn-based tactical battles the most intense and gut-wrenching they have ever been. It doesn’t shy away from RNG, and it can feel quite unfair from time to time. Having played it, I cannot deny that the game has some elements of frustration, but those are also the ones you remember the most: When a rookie with a 20% shot turns a whole battle around, for example. If XCOM left you asking for more, Xenonauts 2 might be the game for you. I can also recommend the first Xenonauts with no regrets.
17 – Desperados III
Before its untimely departure, Mimimi Games left us some of the best real-time stealth tactics games of all time, including their debut title Shadow Tactics: Blades of the Shogun, which was widely acclaimed (by myself included) as the continuation of the lineage that the Commandos series left abandoned in the early 2000s. Then the studio followed with what’s arguably their best game yet, with Desperados III. The Wild West setting and story, paired with larger maps, a lot more options (a lot more guns), and a cast of 5 characters that have their very own particular set of skills, allow players to tackle greater puzzles and overcome larger groups of enemies.
16 – Stirring Abyss
This is the second Lovecraft-inspired video game of the day, and it’s here for a very good reason. You see, Stirring Abyss never got the recognition it deserved. Inspired by The Temple, the player’s submarine and crew are stranded at the bottom of the ocean, and you’re now in survival mode, trying to recover your crewmates, repair the sub, and escape the nightmarish abominations of the depths. It’s a turn-based strategy game where you and your group of divers explore the abyss and encounter secrets that humanity has no business knowing about. These horrors impact your crew, their sanity, and they’ll even learn and mutate from them. It’s a tense game where you have to manage combat, oxygen tanks, and sanity, all at once.
