Yet Another Zombie Defense HD Free on Steam Until July 30

Steam’s Free to Keep promotion is back with another title that costs nothing to claim for your library. This time, players have a limited window to add Yet Another Zombie Defense HD—a 2017 top-down tower defense zombie shooter—to their account before it leaves the offer. The giveaway is set to expire on July 30.

What you get with Yet Another Zombie Defense HD

Yet Another Zombie Defense HD is a 2D, top-down defense game built around a day/night cycle: you construct and prepare your base during the day, then defend it as zombie waves get tougher at night. It also includes “zombie shooter” elements, shifting the moment-to-moment play into active survival as the pressure ramps up.

For co-op groups, the game supports online play for up to four players, and it offers three modes: Defense, Endless, and Deathmatch. The title also supports Steam Workshop, letting players download custom character models and maps to remix the experience.

Genre: top-down 2D tower defense with zombie shooter elements
Gameplay loop: build by day, defend against escalating hordes by night
Co-op: up to four players online
Modes: Defense, Endless, Deathmatch
Workshop: custom character models and maps

Why this giveaway matters for your Steam backlog

Steam’s Free to Keep deals don’t come with advance scheduling, so the main challenge is simply noticing the promotion before it ends. The upside is that once you claim a title, you don’t need to install it immediately—making these giveaways a practical way to grow a backlog without spending money right now.

In this case, the offer is time-bound, so players who want to keep Yet Another Zombie Defense HD permanently in their library should claim it before the July 30 cutoff.

Reception and what players say about its appeal

While Steam’s giveaways sometimes draw criticism for having fewer major AAA titles, this new freebie leans on solid community reception. Yet Another Zombie Defense HD carries “Very Positive” reviews, with players highlighting the addictive gameplay loop and the value of co-op play as reasons to try it.

That combination—defense-focused structure plus cooperative sessions—also makes it a good candidate for players who want something that’s easy to rotate in and out of their library rather than a single, long campaign commitment.

Series timing: the next game is close

Steam’s promotion is tied to the release announcement of the next entry in the series, Yet Another Zombie Survivors. The sequel has been in Early Access since July 2023 and is now scheduled for an August 20, 2026 release.

With that launch date less than a month away, the free giveaway functions as a chance to test the prior game’s formula—especially if you’re deciding whether the series’ co-op defense approach is your kind of gameplay before the newer title arrives.
