Ultimate Zombie Defense, a top-down survival horror title, has dropped to $0 on Steam. This currently free game on the platform has a good overall player rating, is playable on the Steam Deck, and is worth $4.99.

Steam is currently offering a well-rated survival horror title, Ultimate Zombie Defense, for $0. This currently free game features a "Very Positive" rating with over 1,300 player reviews and goes for $4.99 when there's no sale in place.

Released in December 2020, Ultimate Zombie Defense is a horror game known for its real-time action and heavy survival elements. It's designed to offer a top-down perspective, and players can progress the story in solo and co-op modes, supporting up to four players.

As for the game setting, this currently freebie is set in the suburbs of a continental European city. It features a playable area that's 250 km large, and after a catastrophic zombie outbreak, the whole of it has been quarantined. Players are given the role of elite military operatives in the area, and they are tasked to locate and eliminate the source of the infection.

Of course, that's only the core objective, as players also need to build defenses and survive the relentless waves of zombies. Speaking of which, this currently free game on Steam has relatively detailed building mechanics, and the strategic placement of the deployables plays a crucial role in terms of surviving.

Regarding the enemies, Ultimate Zombie Defense sports more than 12 zombie types. Each has a distinct attack pattern, and even experienced players may find it a bit challenging to fight against the bosses in this free Steam game.

Other than that, the game doesn't require a top-of-the-line gaming PC or handheld (1 TB Beelink Ser8 curr. $499 on Amazon), and it even comes with the Steam Deck Playable compatibility rating. Ultimate Zombie Defense will remain a free-to-keep game until July 15, 2025, and those who are interested in giving its story a go can learn more about the title from the video attached below.
