Last Z Survival Shooter Season 4 Guide: Events, Heroes, Buildings & Smart Progression

Last Z Survival Shooter Season 4 brings a huge number of changes, including a brand-new map, different enemies, revised events, and a completely different progression path, and heading into Season 4 without a clear plan will lead to wasted resources, lost time, and falling far behind other players very quickly.

This guide will explain the core content of Season 4, all the new features, the most important mechanics, and the most efficient way to progress, especially for free-to-play and low-spending players.

New Dinosaur Theme

Season 4 features a dinosaur theme, turning the entire map into a green, prehistoric jungle that makes players feel like they have stepped into Jurassic Park with guns.

The familiar normal zombies are gone, replaced by dinosaurs:

• Regular zombies become velociraptors, boomers turn into stegosauruses
• The Fury Lord is replaced by a massive movie-style dinosaur boss.

These changes completely reshape combat, rewards, and the overall progression loop of the season.

 

New Heroes & Battle Passes

Along with the map overhaul, Season 4 introduces 3 brand-new heroes, each with their own exclusive weapon: Yu Chan from Blood Rose, Queenie from Wings of Dawn, and Amber from Guard of Order.

Each hero is released with a separate hero battle pass, followed by three more battle passes for their exclusive weapons, making a total of 6 weeks of battle passes directly tied to these Season 4 heroes and weapons.

Key Point: Missing a hero or weapon during the initial battle pass is not a major setback; after these 6 weeks, the battle passes will rotate to offer hero fragments and exclusive weapon fragments, allowing players to unlock them later. There is no need to panic, rush, or make poor spending decisions out of fear of missing out.

 

Season 4 Glory Wars Rewards

Season 4 also adds Season 4 recruitment tickets, which are used in a dedicated recruitment tab for Season 4 heroes and are mainly obtained through Glory Wars and seasonal rewards.

In Glory Wars, each state is grouped with 3 other states, and the event takes place every Tuesday. Similar to previous seasons, alliances compete against each other to earn season points, with higher rankings earning better rewards including Season 4 recruitment tickets and other valuable seasonal items.

Each alliance receives 3 redesigned dinosaur-themed alliance centers, so placing these centers early and coordinating with the alliance is extremely important for fast progression.

 

Seasonal 4 Buildings Priorities

Seasonal buildings return in Season 4 and are mandatory just like in Season 3. For this reason, players’ top priority at the start of Season 4 should be upgrading bio greenhouses and the biotech lab before anything else.

• The bio greenhouse is the most important building at the start, as it produces fern leaves, one of the main seasonal resources; players can build four bio greenhouses by default and unlock a fifth through wartime investment.
• The second seasonal resource is Cretaceous Scales, obtained by killing NPCs on the map.
• The biotech lab is the most critical early building because it increases virus resistance, which determines the level of dinosaurs players can attack.

Higher-level dinosaurs yield better rewards, more glory points, and more badges, and virus resistance is even more crucial in Season 4 than it was in Season 3, as low virus resistance will lock players out of high-quality rewards entirely.

Players should NOT rush to upgrade the command center, armory, or fortification, as these buildings boost seasonal troop damage, attack, and defense but are far less important than virus resistance early on. Once players can comfortably defeat level 60 dinosaurs, they no longer need to prioritize upgrading the biotech lab and bio greenhouses and can gradually shift resources to other seasonal buildings.

 

Major Season 4 Events

the Ancient Dino

The most enjoyable events in Season 4 is the Ancient Dino event, which takes place every Sunday at 12 Apocalypse Time, where all players attack a massive dinosaur at the same time with no attack limits.

• The top three damage dealers on the first kill receive a unique title; there are five ancient dinos in total—T-Rex, Triceratops, Parasaur, Ankylosaurus, and Plesiosaur—each with its own title and reward set.
• Even players who do not rank high earn participation rewards including fossils, tactical plug-in chests, and speedups.

Fossils are used in the fossil album with 20 fossils in total, and completing the album rewards players with orange hero fragments, exclusive equipment fragments, and ancient dino eggs, while duplicate fossils can be exchanged for ancient dino eggs. These eggs are used in the bio institute shop that opens only on Saturdays and Sundays.

The shop sells exclusive equipment fragments, orange hero fragments, badges, speedups, and resources, with 14 free refreshes available every weekend, so careful planning is essential.

 

Hatch of Legends

Hatch of Legends lets players raise a dinosaur, choosing between T-Rex, Triceratops, and Kronosaurus, unlocking a vehicle troop skin at level 16 with only one skin available per season.

All dinosaurs grant the same bonuses of 1% troop attack per level up to 30% at level 30, making the system very free-to-play friendly.

 

Predator squads Combat

Predator squads are regular NPCs on the map up to level 200, with rewards for 2 kills per day from Monday to Saturday and 5 kills on Sunday, dropping seasonal resources, ancient dino eggs, blueprints, hero exp, and pine cones.

 

The Dino Rescue event

On Sunday, the Dino Rescue event takes place with a special boss called the black market guardian that reaches level 350 and requires rallies, with rankings based on damage dealt and statewide achievements rewarding all players, emphasizing cooperation.

 

Dino Egg Defense

Dino Egg Defense is similar to zombie siege, where players defend their headquarters against waves of dinosaur attacks, with completion rewards being more important than rankings and the final completion reward granting up to 14 golden wrenches.

 

Trade Hubs & Diamond Strategy

The most controversial feature of Season 4 is trade hubs, which appear at 11 Apocalypse Time on Mondays, Wednesdays, and Fridays. The first week is state-only, after which cross-state competition begins.

Alliances can capture hubs to generate diamond tax envelopes and unlock exclusive shop items, with alliance members getting early access before hubs open to the public for more diamonds.

The trade hub shop sells badges, orange hero fragments, plug-in chests, speedups, steel, and power cores, all costing diamonds, making Season 4 less free-to-play friendly than Season 3.

Tips: Players preparing for Season 4 should save diamonds now and prioritize buying badges and exclusive fragments.

 

How to get more resources in Season 4?

Season Journey

The Season Journey provides powerful bonuses including extra virus resistance, increased fern leaf production, speedups, badges, orange hero fragments, mastery reset passes, and most importantly, double glory chest rewards.

Glory Points

Glory points are earned by killing dinosaurs, with higher-level dinosaurs giving more glory.

Players can collect a glory chest every 8 hours that grants up to 148 badges at max level, which doubles to nearly 300 badges every 8 hours or about 900 badges per day with the Season Journey active.

The glory leaderboard itself has no ranking rewards, and the real benefit is faster early progression. Players who cannot defeat high-level dinosaurs alone should join rallies started by stronger players and still earn glory points, which is one of the most underrated free-to-play strategies.

 

Bones and Eggs Boom

Later in the season, a permanent bonus called Bones and Eggs Boom unlocks, doubling Cretaceous Scales and ancient dino eggs and lasting until the end of Season 4, greatly speeding up mid-season progression.

 

Wartime Investment

Wartime investment can be purchased up to 4 times and becomes permanent once fully purchased, offering increased fern leaf output, 100 extra virus resistance, the fifth bio greenhouse, and increased march speed against velociraptors.

Tips: It provides a strong early advantage but is NOT mandatory, and free-to-play players can progress well without it.

 

Hero Level Swap System

Season 4 also features a hero level swap event that runs the entire season, allowing players to permanently swap hero levels and skill levels between two heroes.

This means all investment from an old hero can be transferred to a new Season 4 hero without losing progress, making it one of the most powerful systems for free-to-play players.

 

Conclusion

In simple terms, the early game of Season 4 focuses on bio greenhouses and the biotech lab, switching to support mastery, and raising virus resistance. The mid-game involves joining rallies, farming glory, and collecting fossils and eggs. The late game centers on trade hubs, exclusive fragments, and completing the Season Journey.

Season 4 demands more planning, alliance coordination, and smart resource management than any previous season, and following this structured approach will help all players prepare effectively and progress smoothly.
