About Z Tools

What is Z Tools?

Z Tools is a collection of interactive planners, trackers and reference guides for players of Last Z: Survival Shooter, a mobile zombie survival strategy game. The site exists to make the game's data legible — badge costs, tank wrench costs, building requirements, hero skills, event timings — so players can plan their progression instead of digging through patch notes.

Everything here is free to use, and no account is required — your progress saves locally in your browser. If you want it to follow you between devices, myZ is an optional account that does exactly that and nothing else. Alliances can also have a private space of their own for guides, notices and a shared calendar.

What's on the site

• Alliance Duel Calendar — live 7-day event cycle with countdowns and 35+ timezones including Apocalypse Time.

• Alliance Spaces — a private area for your alliance: guides, notices, a shared calendar and a weekly vault rota, visible to members only.

Who is this site for?

Z Tools is built for active players who want to plan more than guess. The interactive trackers (Research, Tank Modifications) assume you'll be opening the site repeatedly across weeks or months to mark progress. The reference tools (Heroes, Buildings, HQ Levels) are designed for quick spot-checks — what does this hero's skill actually do, how much zent does HQ 25 cost, when does the City Walls unlock? The wiki articles are for the longer reads: how Capital Clash actually works, how to position in Canyon Clash, when to break a shield.

Most users are between HQ 18 and HQ 30 — the point in progression where the game's UI hides important data behind grindy menus and where strategic decisions start to matter more than passive growth. The data-driven tools are server-agnostic, so they are just as useful whichever server you play on.

Who runs Z Tools?

Z Tools is built and maintained by BD Digital Creations, a UK-based independent web development studio. The site began as a single event calendar for one alliance on Server 277 and grew into a broader toolkit as more features were requested by the community.

It's a personal side project rather than a commercial venture. Content is written from the perspective of active Server 277 players, so strategy notes reflect that server's current season — but the tooling (badge costs, hero skills, building levels) is general to the game and useful on any server. Game-data updates happen within a few days of each major patch.

How the site is built

Z Tools is a fast, static website delivered over HTTPS. Tool progress saves to your browser's local storage by default, and is only copied to a database if you opt in by signing in. The site is designed to load quickly on mobile (under 2 seconds for the homepage on a budget Android), pass Core Web Vitals, and work without JavaScript wherever possible.

Accessibility is a first-class concern: every interactive element is keyboard-reachable, the colour palette meets WCAG 2.1 AA contrast, an accessibility panel lets users adjust font size, contrast, animations and cursor size, and a dyslexia-friendly font option is built in. The site is also translated into 19 languages — English, Spanish, Chinese (Simplified), Hindi, Arabic, French, German, Japanese, Korean, Portuguese, Russian, Turkish, Vietnamese, Thai, Indonesian, Polish, Ukrainian, Italian and Urdu — using a runtime DOM-walker translator that preserves game-specific proper nouns in their original form.

How we keep it free

Running the site has small costs (domain, hosting, development time). We cover those through:

• Affiliate links (Hostinger, Proton VPN) that pay a small commission at no extra cost to you.
• Voluntary donations via Ko-fi and PayPal if you'd like to support development directly.

No part of the site requires payment to access.
