Zombie Apocaclicks

Zombie Apocaclicks is a zombie-apocalypse clicker hosted entirely on CodePen by Anthony Costantino, who goes by u/Xxt0NyCxX. You click to generate Drops of Blood, the game's currency, and spend them on Survivors, Scouts and Turret generators that automate the bloodletting while the apocalypse hums along in a browser tab. It is alpha software, v0.6.9 being the latest known release, and it is catalogued here because a functioning idle with a real upgrade tree deserves a record even when its host is a code-sharing site.

What the loop feels like

You click, blood drips into the ledger, and the first Survivors start generating it for you. That's Zombie Apocaclicks.

The generator ladder is the whole economy: Survivors as the baseline income, Scouts as the next tier, Turrets as the heavy automation, each purchase nudging the apocalypse from manual labor toward background process. The alpha label is honest about the incomplete state, and the upgrade tree, real as it is, reflects that: functional, legible, and visibly a work in progress. That's Zombie Apocaclicks, a genre skeleton with the flesh still arriving.

The CodePen story

CodePen as a game platform is unusual and worth noting. Most CodePen games are demos or experiments, front-end portfolio pieces with a rocket emoji and a weekend's lifespan; Zombie Apocaclicks is a functioning idle with a real upgrade tree living at a pen URL, which makes it one of the more committed residents of that odd neighborhood. The entry's research is entirely first-party: the game's own rendered DOM was the primary source, the mechanics were read from the live pen, and the twelve sprites in the entry, the hero zombie, five zombie shots and six UI icons, were pulled from that DOM and saved with metadata sidecars. No third-party coverage exists anywhere: AI mode finds nothing, no reviews exist, and the community wiki listing is the only external reference, which is why this entry reads like field notes rather than a review.

The v0.6.9 release notes and the pen's edit history sketch a development arc that never left alpha: iterative generator additions, UI patches, and balance passes, the solo developer publicly iterating in the open in a way that only a CodePen host permits. The resource economy follows the apocalypse's own logic, blood as currency being both the genre's joke and its constraint, with Survivors, Scouts and Turrets mapping cleanly onto the generator roles other idles give to grandmas and farms. As an artifact it belongs to a specific moment in the browser-idle lineage, when the tools got simple enough that a full incremental could live at a shareable URL with no repository, no store page, and no distribution beyond a link in a subreddit post.

Playing it today

Free on CodePen, playable in any browser, with the usual caveats of alpha web software: it persists at the mercy of the pen's owner and the platform's goodwill, and there is no roadmap to consult. For the apocalypse's bigger-budget residents, the catalog's zombie shelf runs darker and deeper, and War Factory covers the automate-the-defense fantasy at full scale.

The verdict

An alpha curiosity for idle game archaeologists: a real upgrade tree living on a code-sharing site, documented from its own source code because nobody else would. Click the blood, mind the pen, and file it under web archaeology.
