If you want a free Steam game, act now: Yet Another Zombie Defense HD is available to claim at no cost, but the offer runs only until July 30. The game blends top-down tower defense with zombie-shooter nights and supports online co-op—so it’s a solid backlog add for anyone who likes to play with friends.
What changed: Steam’s latest Free to Keep giveaway
Steam’s Free to Keep promotion is live again, offering another title to add to your library without paying. This time, the featured game is Yet Another Zombie Defense HD, a 2017 tower defense zombie shooter. Steam users can claim it for free during the promotion window, and the title is described as having “Very Positive” reviews from players.
Because Free to Keep deals aren’t announced in advance with a clear schedule, the promotions can be easy to miss. Steam also doesn’t require immediate installation after claiming, which makes the program useful for players building a backlog over time—especially if you tend to wait for the right moment to play.
Who’s affected: Steam players who want a free co-op defense game
The giveaway is for Steam users who want to claim Yet Another Zombie Defense HD before it disappears. The game is a top-down defense experience where you set up your base during the day and then defend against increasingly difficult zombie waves at night.
The title also includes zombie-shooter elements tied to those nightly defense phases. For groups, online co-op is supported for up to four players, and it spans three modes: Defense, Endless, and Deathmatch. Players looking to customize their experience can also use Steam Workshop support, including downloads for custom character models and maps.
Given the “Very Positive” reception and the emphasis on co-op gameplay, the giveaway is particularly relevant for players who want a co-op-friendly game they can claim now and play later.
What comes next: deadline, plus why this giveaway is timed
The practical next step is simple: claim Yet Another Zombie Defense HD on Steam before the promotion ends on July 30. The source indicates you effectively have about a week to secure the tower defense title completely free of charge.
The developer also frames this Free to Keep promotion as a celebration tied to the release date announcement of Yet Another Zombie Survivors, the newest entry in the series. That newer game has been in Early Access since July 2023 and is set for an August 20, 2026 release date. With that launch approaching, the current giveaway functions as a chance to try the prior game’s formula and decide whether it clicks before the next release.

Expert View
This is the kind of Free to Keep drop that makes the program feel worthwhile: a co-op-focused tower defense with Workshop customization, plus a strong player sentiment signal. The main risk for players is simply the deadline—since Steam doesn’t reliably advertise these promotions, you’ll want to claim it immediately if you’re even slightly curious. If you enjoy co-op sessions and defensive gameplay loops, it’s a good “grab now, play later” addition.
