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.

New Alliance spaces: a big upgrade
Spaces can now hold live blocks — countdowns, the Apocalypse clock, today’s duel, upcoming events, the next vault drop and gift codes — that keep themselves up to date. Invite members with a link instead of an email, let them comment on notices and guides, and see exactly what is new since your last visit. Leaders choose what posts to Discord, with an optional reminders channel and a Monday summary, and the editor now works like a document, with templates and undo. Learn more →

New New tools: S4 and S5 tile planners
The Season 3 tile planner now has company. Plan buildings, priorities and per-level costs for Season 4 (Dinosaur Origin) and Season 5 (Moonlit Elegy). Costs are not published anywhere yet, so the tables start empty for you to fill in, and your progress syncs if you are signed in. 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.
