Alliance Spaces
A private area for your alliance’s guides, notices and shared calendar. Visible to its members only, and free.
Browse the directory
See which alliances have a space, by state. The directory is public; what’s inside each space is for its members alone — rules, event plans, notices and a calendar shown in every member’s own timezone.
→Get one for your alliance
Tell us your in-game name, state, alliance tag and rank, and we verify it by hand against the alliance in game. If your alliance has a space you join it; if not, we create one and make you its owner.
→Guides & Community
Deep-dive strategy guides for every part of the game.

Update Lucky Rose updated for this week

New Alliance Spaces are out of beta
The beta label is gone. Ten alliances across ten states now run their space day to day — guides, notices, a shared calendar in everyone’s own timezone, roles and an audit trail — and it has been steady enough for long enough to stop calling it an experiment. Nothing changes for the spaces already running, and it is still free. Development carries on, but the parts your alliance leans on are settled, and anything disruptive gets an email to owners first rather than arriving as a surprise. Any alliance can still ask for one.

Update Research Trees — a tenth tree, verified data and visible dependencies
Shooter Training joins the planner: 12 nodes and 1,357,180 badges, the tree that unlocks after 100% Field. Every badge cost has been checked — a handful were corrected, and the few values not yet confirmed are marked TBC rather than guessed. The trees also now look like trees: lines show what unlocks what, turning green as you complete prerequisites, with Requires and Unlocks buttons on every node, arrow-key navigation and previous/next tree switching. Your saved progress carries over untouched. Learn more →

New v3.1 — myZ and Alliance Spaces (beta)
Two big additions, both marked beta: they work and they are live, but details will still change. myZ is an optional account that carries your tool progress between devices — no password, just a code by email. Alliance Spaces gives an alliance its own private area for guides, notices, notes and a shared calendar, and any alliance can now ask for one. Neither is required: every tool works exactly as before without signing in to anything. Learn more →

New myZ — your progress, on every device (beta)
Tick research nodes on your laptop and find them already ticked on your phone. There is no password: type your email, we send you a code, and that is the whole sign-in. Entirely optional — every tool still works without it, saving to the browser you are using. You can see everything stored for you, download it, or delete it from your account page. Learn more →

What is Z Tools?
Z Tools is a free community companion site for Last Z: Survival Shooter, the popular mobile zombie survival strategy game by Florere Game. We provide interactive tools and comprehensive guides to help alliance players maximise their progress.
Strategy notes and event timings come from Server 277, where the site began. The tools themselves — the calculators, planners and wiki — are general to the game and work the same wherever you play.
