🦕 Season 4: Dinosaur Origin

Complete alliance guide — the longest, deepest, and most strategic expansion in Last Z so far.

Adapted for FFz from public Season 4 coverage. Always double-check in-game timers (Apocalypse Time).

At a glance

  • Duration

    91 days (13 weeks) of Jurassic meta.

  • Map theme

    Full Jurassic Jungle overhaul — undead nodes gone (e.g. raptors replace basic zombies; stegos replace Boomer-style elites; legacy Fury Lord style world bosses shift to dino bosses).

  • New monsters

    Velociraptors & Stegosauruses replace classic farms.

  • Specialization

    Cap raised to Level 70 (new skills from 51+).

F2P — read this first

Season 4 is much less F2P-friendly than Season 3. Trade Hubs burn Diamonds.
Stockpile Diamonds before S4 — avoid random spending in the first weeks.

Brand new features

  • All-new map

    Green Jurassic Park–style terrain. Full ecological overhaul.

  • 3 seasonal heroes

    Yu Chan, Queenie, Amber — each with pass + exclusive weapon.

  • Hatch of Legends

    Hatch, feed, and raise a dino up to Lv.30 (+30% troop ATK).

  • Trade Hubs

    Diamond markets Mon/Wed/Fri — badges, hero pieces, speedups.

  • Ancient Dino Boss

    Every Sunday 12:00 AT — unlimited entries, top 3 get a Title.

Passes & investments

  • Season Journey

    ~$24.99 USD · Core battle pass

    • 2× 8-hour Glory Chest rewards
    • Extra virus resistance · more Fern Leaves · speedups · badges
    • Orange hero / choice fragments · mastery reset tools

    • +10% hourly Fern Leaves
    • +100 virus resistance
    • Unlocks 5th Bio Greenhouse

Value focus (F2P / low-spend)

Highest leverage for actives: Season Journey (double glory badges) and Wartime Investment (5th greenhouse + resistance).
Wartime is a strong early edge but not mandatory — F2P can clear S4 without it if diamonds and Lab/Greenhouse discipline are solid.

Season 4 heroes

Three heroes land over the opening ~6 weeks: typically 3 hero passes + 3 exclusive-weapon passes (six weeks of S4-tied tracks).

  • Yu Chan

    Blood Rose · Weapon: Wyrm Wrath

    First S4 drop — her pass opens the intro schedule.

  • Queenie

    Wings of Dawn · Weapon: Firefall

    Second drop — high-scaling burst / damage engine.

  • Amber

    Guard of Order · Weapon: One-Hit Kill

    Final drop — basic-attack damage & single-hit multipliers.

Hero Faction Exclusive weapon Role
Yu Chan Blood Rose Wyrm Wrath Season opener
Queenie Wings of Dawn Firefall Burst DPS
Amber Guard of Order One-Hit Kill Auto-attack / single-hit

Missed the release window?

After ~6 weeks, passes shift toward generic choice shards. Missing day-one is not fatal — catch up later.

Recruitment & Level Swap

S4 Recruitment Tickets & Glory Wars

Tickets work only on the Season 4 banner. Main sources: Glory Wars (every Tuesday) and seasonal milestone chests.
In S4, your state is grouped with 3 other states for the season grouping — alliances compete for season points and ticket/reward tiers.

Hero Level Swap — full season

Active all 13 weeks. Permanently swap levels + skill trees between two heroes. Move investments from outdated units into S4 heroes with zero wasted progress.

Exclusive infrastructures

Built only in the seasonal instance. Fuel upgrades with Fern Leaves and Cretaceous Scales.

Construction priority

  • Biotech Lab

    Priority #1 · Global Virus Resistance

    Decides the max dinosaur level your squads can challenge without lethal debuffs.
    Too low resistance → unsafe fights, wasted marches, bad loot efficiency.
    Higher safe tiers → glory, badges, better chests. Optional once Lv.60 dinos are comfortable debuff-free.

  • Bio Greenhouse

    Priority #2 · Passive Fern Leaves

    Funds almost every seasonal building.
    4 plots Day 1 · 5th needs Wartime Investment.

  • Command Center

    Seasonal troop damage %

    Only after Lab + Greenhouses are healthy and self-sustaining.

  • Armory & Fortification

    Attack / defense · 2 of each base

    3rd Armory via Combat spec ~Lv.60+. Upgrade symmetrically.

  • Alliance Centers ×3

    Territory, borders, War of Glory anchors

    Dinosaur theme · place fast with officers on prime nodes.

Classic launch blunder

Do not dump build speedups into Command Center / Armory / Fortification in hour one while Biotech Lab is neglected.
Low Virus Resistance = lethal debuffs on high dinos + locked out of premium map farms.

World map & raids

Full ecological overhaul. Shared stamina reward cap: 15 global drops per day — choose targets carefully.

Daily farm priority

  • Velociraptors — #1

    S4 “basic zombies.” Main Cretaceous Scales + baseline glory.
    Always hit the highest level your resistance allows.

  • Stegosauruses — #2

    Elite-style (old Boomers). Ancient Dino Eggs + scales.
    Still count toward the 15/day shared cap.

Heavy targets

  • Predator Squads

    Max Lv.200 · components, eggs, blueprints, Hero EXP, Pine Cones

    2 kills/day Mon–Sat · 5 on Sunday.

  • Black Market Guardian

    Max Lv.350 · Sunday Dino Rescue · endgame alliance rally

    Leaderboard damage · state-wide achievements pay everyone: exclusive gear, orange pieces, tickets, fuel, Dino Feed.

  • Dino Rescue (Sunday)

    High-coordination Sunday raid event (group content)

    The Black Market Guardian is the flagship target. Not a solo Velociraptor farm — rally tags, callouts, full participation.
    State achievements reward all players, so cooperation beats solo carry culture.

Dino Rescue vs Predator vs Guardian

Track Role
Velociraptor / Stego Daily stamina economy (scales, eggs, glory) · shared 15/day reward cap
Predator Squads Limited daily kills (2 Mon–Sat · 5 Sunday) — components, eggs, Pine Cones
Dino Rescue Sunday coordinated event — Guardian + state achievements
Black Market Guardian Lv.350 rally boss inside Dino Rescue — damage ranks + server loot

Glory economy

Every 8 hours → collect a Glory Chest:

Season Journey Badges per chest (approx.)
Without pass up to ~148
With pass ~2× → ~300 (~900/day)

No personal glory rank rewards

Leaderboard place does not pay individuals. Only badge velocity matters.
Cannot solo high dinos? Rally with whales — same glory values.

Bones & Eggs Boom (mid-season)

Server-wide modifier: doubles Cretaceous Scales & Ancient Dino Eggs from map nodes until season end.
When it lights up — burn stamina items hard.

Event schedule

  • Ancient Dino

    Every Sunday · 12:00 AT

    Unlimited attacks · top 3 damage on the first kill of that species on your server → unique permanent Title
    Weekly rotation (5): T-Rex · Triceratops · Pterosaur (Parasaur) · Ankylosaurus · Demitradon
    Drops: fossils, Tactical Plug-in Chests, speedups · top ranks get denser chests/diamonds; participation still feeds the album.

  • Dino Egg Defense

    Prehistoric Zombie Siege rework

    Prioritize full clear / survival over pure rank.
    Max completion reward: up to 14 Golden Wrenches (tank/wrench progression material).

  • Trade Hubs

    Mon / Wed / Fri · 11:00 AT · typically 3 hub levels

    Week 1 state-only → then cross-state. Capture hubs for diamond tax envelopes + exclusive shops.
    Alliance members get early shop access before public open — plan diamond spend (badges & exclusive frags first).
    Shop (Diamonds only): badges, orange hero pieces, plugin chests, speedups, steel, power cores.

  • Fossil Album

    20 unique fossils (mainly Sunday Ancient Dino)

    Full set → orange frags, exclusive gear mats, eggs. Duplicates → Ancient Dino Eggs.
    Many builds also track album milestone points on every fossil (including dupes) for intermediate chests.

  • Bio Institute Shop

    Sat & Sun · currency: Ancient Dino Eggs

    Up to 14 free refreshes per weekend — budget eggs carefully.

Ancient Dino — be online

Active servers melt the boss in ~5–15 minutes. Be ready before 12:00 AT.
Titles are first-kill of that species on the server only — once that dino has been first-cleared, later weeks of the same species do not re-issue the title.

Hatch of Legends

Pick one species · raise to Level 30.

  • Power curve

    +1% global Troop Attack per level → +30% at max.

  • Species

    T-Rex · Triceratops · Ankylosaurus
    Same stats — pick is cosmetic only.

  • Level 16 reward

    Permanent exclusive vehicle skin for your species.

  • Upkeep

    Dino Feed + Pine Cones from dailies & map.
    One dino per account · generally F2P-friendly.

Specialization Hall (Lv.70)

S3 talents carry to 50. From 51, new S4 skills unlock.

Golden rule — early season

Reset and go 100% Support in the opening weeks. Construction speed, map economy, and Virus Resistance layers win the early game.

Talent Effect
Resource Plunder +2% resources from map NPCs, Stegos, bosses
Mastery Accelerator +2% Spec EXP per kill (×5 → +10%)
Time Compression −30 min all build queues (×5)
Construction Blitz Permanent % seasonal build speed

Foraging Matrix Permanent map gather speed
Cap Breakthrough +5 mastery for other paths
Talent Effect
Vanguard Teleport 1 energy / 72h (store 2); free Advanced TP

HQ Bastion +2% ATK/DEF defending home
Fortified Logistics +1 seasonal defensive building
Heavy Armaments +1 Armory cap → 3rd Armory
Field Devastation Field / truck / canyon damage

When to flip to Combat

After Lab / Greenhouses stable around Lv.60+, Combat tools (Teleport, Blitz Rally, 3rd Armory) shine in field and cross-server.

Alliance rankings & Glory Wars

Points ≈ members’ Glory + captured strategic cities
(city points stay even if lost later)

Glory Wars structure (S4)

  • Every Tuesday
  • Your state is grouped with 3 other states for the season
  • Alliances compete for season points → higher brackets = better rewards (S4 recruitment tickets, blueprints, packs)
  • Wins can plunder / shift points vs enemy brackets — show up for war days
Rank Title Reward tier
#1 Supreme Legion Top tickets, blueprints, massive packs
#2–3 Dawn Army Premium runner-up
#4–5 Glorious Pioneer High-tier growth mats
#6–10 Protection Oath Strong top-10 server
#11–20 Expeditionary Alliance Solid competitive baseline
#21–50 Wasteland Legion Catch-up developing alliances
#51–999 Wasteland Guardian Standard participation
