Last Z Season 4 Guide | Dinosaur Origin

📋 Introduction

Season 4 is the longest and most complex yet — 91 days (13 weeks). The map transforms into a prehistoric Jurassic jungle. Zombies disappear and are replaced by dinosaurs. There are more events, new systems, and greater strategic depth than any previous season.

⚠️ F2P WARNING: S4 is less free-to-play friendly than S3, mainly due to Trade Hubs requiring diamonds. It is strongly recommended to save diamonds before entering S4.

🎯 What's New in S4:

Brand new map — green jungle, Jurassic Park theme
3 new heroes: Yu Chan, Queenie and Amber
New system: Hatch of Legends (raise a dinosaur)
New system: Trade Hubs (commerce hubs)
New event: Ancient Dino (massive boss every Sunday)
New event: Dino Rescue + Black Market Guardian
New: Fossil Album (collection of 20 fossils)
New: Hero Level Swap (level exchange system)
Specialization extended to level 70

🦸 Season 4 Heroes

3 new heroes are introduced, each with their own battle pass and exclusive weapon. Released in order during the first 6 weeks.

Yu Chan

🔴 Blood Rose

Arma: Wyrm Wrath

First hero released. Her battle pass is the first of the season.

Queenie

🔵 Wings of Dawn

Arma: Firefall

Second hero. Massive damage with high damage factor.

Amber

🟡 Guard of Order

Arma: One-Hit Kill

Third hero. Normal attack boost and per-hit damage.

💡 TIP: If you miss a hero or weapon during their initial battle pass, it's not the end. After 6 weeks, passes rotate into hero and exclusive weapon fragments — you can still unlock them later.

🎫 S4 Recruitment Tickets:

Used in an exclusive tab to recruit S4 heroes. Mainly earned through Glory Wars and seasonal rewards.

🔄 Hero Level Swap (Full Season):

You can swap hero levels and skill levels between two heroes permanently. This allows you to transfer all investment from an old hero to a new S4 hero without losing progress — one of the most powerful systems ever added to the game.

🏗️ Season 4 Exclusive Buildings

Only available during S4. Upgraded with Fern Leaves and Cretaceous Scales.

🎯 Priority Order:

1

🧬 Biotech Lab

2

🌿 Bio Greenhouse

3

🏰 Alliance Centers

4

⚔️ Power (level 60+)

🧬 Biotech Lab PRIORIDAD #1

Function: Increases your virus resistance — determines which level of dinosaurs you can attack.

Why it's critical: Higher dinosaur level = more glory points, more badges, better rewards. Without high virus resistance, you are locked out of good rewards.

When to stop: Once you can defeat level 60 dinosaurs, upgrading it is no longer mandatory for progression.

🌿 Bio Greenhouse PRIORIDAD #2

Function: Produces Fern Leaves — the main resource for upgrading buildings.

Quantity: 4 by default. The 5th unlocks with Wartime Investment.

Strategy: Build all 4 from the very start of the season.

⚔️ Command Center

Function: Increases seasonal troop damage.

When to upgrade: Only after Biotech Lab and Bio Greenhouse are at a good level.

🛡️ Armory (x2)

Function: Increases seasonal troop attack.

Note: You can build up to 2. A third unlocks with Combat specialization level 60+.

🏰 Fortification (x2)

Function: Increases seasonal troop defense.

Note: Also up to 2 units. Upgrade alongside Armory to balance offense/defense.

🏯 Alliance Centers (x3)

Function: Required for Glory War and alliance progression. Redesigned with dinosaur theme.

Strategy: Place them as early as possible — teamwork is essential.

⚠️ COMMON MISTAKE: Do not rush Command Center, Armory or Fortification early. They are useful, but virus resistance comes first. Without it, you cannot attack good-level dinosaurs.

📦 Key Resources:

🌿 Fern Leaves

Produced in Bio Greenhouses. Main resource for upgrading all seasonal buildings.

⚖️ Cretaceous Scales

Obtained by killing NPCs on the map. Secondary resource equally critical for buildings.

🦖 NPCs and Raid System

The map changes completely. Zombies are replaced by dinosaurs. You have a limit of 15 daily rewards total — prioritize correctly.

🗺️ Map NPCs:

🦖 Velociraptors PRIORITY #1

Equivalent to: Regular zombies from previous seasons.

Reward: Cretaceous Scales + glory points.

Strategy: Your main daily source. Always attack the highest level you can.

🦕 Stegosauruses PRIORITY #2

Equivalent to: Boomers from previous seasons.

Reward: Ancient Dino Eggs + Cretaceous Scales.

Limit: 15 daily rewards (shared with Velociraptors).

🦅 Predator Squads

Max level: 200 on the map.

Rewards: Seasonal resources, Ancient Dino Eggs, Blueprints, Hero EXP, Pine Cones.

Limit: 2 kills/day (Monday–Saturday) · 5 kills on Sundays.

🦣 Black Market Guardian DOMINGO

Max level: 350 — requires rally.

When: Sundays only — Dino Rescue event.

Ranking: Based on damage dealt. State achievements give rewards to everyone.

🏆 Glory System:

Killing dinosaurs generates Glory Points. Higher level dinosaurs give more glory. Every 8 hours you can collect a Glory Chest:

Without Season Journey: up to 148 badges per chest
With Season Journey: rewards doubled → ~300 badges every 8h → ~900 badges/day
There is no ranking reward on the glory leaderboard — what matters is progressing faster to earn more badges sooner
If you can't defeat high-level dinosaurs alone → join rallies from stronger players and you'll still earn glory

💡 Bones & Eggs Boom: A permanent bonus that unlocks mid-season. Once active, it lasts until the end and doubles Cretaceous Scales and Ancient Dino Eggs obtained. Makes mid-game progression much faster.
