The Top 7 Must-Buy Games During Steam Tower Defense Fest 2026

The Steam Tower Defense Fest 2026 is now live, running from March 9th to March 16th, and it’s shaping up to be the biggest year yet for tower defense games! Steam has been hosting a lot of events lately – after the huge Steam Next Fest with over 3000 games, the PVP Fest, and a Board Game Fest, it’s now time to enjoy the Steam Tower Defense Fest!

This guide highlights seven key books that every library should have.

7 – Thronefall

Thronefall is a fast-paced strategy game that’s easy to pick up but surprisingly complex. It simplifies the traditional real-time strategy experience, making it incredibly addictive. During the day, you focus on building up your kingdom’s economy and defenses. At night, you take direct control of your king to command troops and defend against large waves of enemies. Whether you prefer careful planning or intense action, Thronefall offers endless replayability.

  • Historic Low Price: Currently 35% off ($8.44) during the Fest, matching its lowest price point for the full 1.0 version.
  • Steam Deck Perfection: Flawless Steam Deck Verified rating for 2026.
  • Game’s Future: The game was acquired by Mythwrigh, giving the two-person team even more resources to expand their title.

6 – Bloons TD 6

Even in 2026, Bloons TD 6 is still one of the best tower defense games available, thanks to its deep gameplay and ongoing updates. While the graphics are bright and cartoonish, don’t let that turn you off – it’s a game worth playing. You can enjoy figuring out the best combinations of heroes and powerful upgrades for challenging events, or simply team up with friends in four-player co-op to pop balloons. It’s easy to pick up and play, packed with content, and surprisingly affordable, but be warned – the addictive gameplay will keep you coming back for more!

  • Historic Discount: It is currently 60% off ($5.59) during the Tower Defense Fest, one of the best value-to-content ratios on the entire Steam store.
  • Massive New Content: The February 2026 update added more content, the game is still in active development.
  • Rock-Solid Performance: While rated “Playable” on Steam Deck (due to the occasional need for the on-screen keyboard), it is perfectly optimized for 60FPS handheld play even during chaotic high-round matches.

5 – The King Is Watching

In the roguelite kingdom builder, The King Is Watching, your focus is the most important resource. This unique mechanic means your subjects only work when you directly look at them on the screen. It transforms typical tower defense and base-building into a fast-paced challenge of deciding what needs your attention right now – do you train soldiers or gather food? It’s a game that’s simple to pick up, but incredibly difficult to truly master, offering a compelling and addictive gameplay loop.

  • Historic Discount: Pick it up for 35% off ($9.74) during the Fest, or grab the “Roguelike Tower Defence Gems” bundle to stack even more savings.
  • Massive Free Content: The recent “Dark Realm” update (March 2026) added a whole new map, “Nether Runes,” and six legendary bosses for no extra cost.
  • Steam Deck Ready: While officially rated “Playable” due to small text, recent community patches and SteamOS 3.7 updates have made the “Gaze” controls feel incredibly intuitive on trackpads.
