Buildings in Last Z

Explore each building's functions, its role in your base, and how to prioritize them. Use the filters to browse by category.

Last Z has over 25 buildings divided into categories: Resources, Attack & Defense, Troops, Missions, and Others. Not all of them are equally important — some are critical from day one, while others can be ignored for weeks without affecting your progress.

Resource buildings like the Sawmill, Farm, and Production Center are your economic engine — without materials you can't build anything. Attack & Defense buildings like the Wall and Toxic Fog Garden determine how much you can resist and how hard you hit. Troops buildings like the Military and recruitment fields define the size and variety of your army.

My general recommendation: Laboratory and Wall always first — they're requirements for almost everything else. Then the faction building that matches your main heroes, and keep your recruitment fields leveled evenly. Use the ⭐ Important filter to see priority buildings with my personal tips.

Seasons
Lumber Mill

Lumber Mill

The Sawmill produces wood automatically over time. It's one of the most used resources for building and upgrading — level it up regularly so production doesn't bottleneck your progress.

Farm

Farm

Without food you can't train or maintain your army. The Farm is your main food source — the higher its level, the faster you produce and the less you depend on gathering from the map.

Foundry

Foundry

The Foundry produces alloys, an essential resource for crafting and upgrading hero equipment. If you want well-equipped heroes, you need this building running at a good level.

Training Camp

Training Camp

The Training Field increases the number of troops you can train at the same time. The higher the level, the more efficient your soldier production — ideal for replenishing troops quickly after a battle.

Residencia

Residencia

The Residence expands your base's population limit. Without enough population you can't have more troops — if you notice you can't recruit more soldiers, this building probably needs an upgrade.

Production Center

Production Center

The Production Center boosts all your resources at once. It's a support building that enhances your base's overall output — don't underestimate it when you need to scale up fast.

Wall

Wall

The Wall is one of the buildings that takes the longest to upgrade in the entire game — and it's a mandatory requirement for leveling your HQ at several key milestones. My advice: always keep it in your construction queue. The higher your Wall, the more attacks you can withstand before your base gets broken into.

Formation I

Formation I

Not as urgent as the Wall or the Garden, but don't ignore it. Formation I is your main attack — the higher its level, the more power your first formation has in combat. Prioritize it over Formation II and III, which are secondary. Keep it at a solid level and you'll feel the difference in every battle.

Formation II

Formation II

Formation II is your second line of attack. While not as urgent as Formation I, don't neglect it — in long battles and Alliance VS, having a strong second formation makes a real difference.

Formation III

Formation III

Formation III completes your offensive arsenal. Give it less priority than the first two, but once your Formation I and II are at a good level, leveling Formation III gives you an extra edge in alliance events.

Toxic Fog Garden

Toxic Fog Garden

If you're F2P and your first formation is Crimson Rose, this building is your number one priority. Leveling it up increases your troop capacity for that faction — and Crimson Rose heroes are the easiest to acquire early in the game. If your attack power feels low, the Toxic Fog Garden is probably the culprit. Upgrade it before anything else.

Steel Factory

Steel Factory

The Steel Factory boosts ATK and DEF for Guardian of Order faction troops. If you use heroes from that faction in your formation, this building is a priority for you.

Dawn Tower

Dawn Tower

The Dawn Tower powers up the Shadow Hunters faction. If your main or secondary formation uses Shadow Hunter heroes, keep this building leveled alongside your troops.

Militar

Militar

Give this building a lot of priority. The Military Center determines how many soldiers you can have in your base — and more soldiers means more defense power on your Wall and more overall power in combat. It's a direct chain: higher Military level → more soldiers → more power. If your defense feels weak, this is a big part of the problem.

Restaurant

Restaurant

The Restaurant increases troop morale and movement speed. While not the most urgent building, at higher levels it makes a difference in reaction speed during war events.

Shooting Range

Shooting Range

The Shooting Range — along with the other 2 recruitment fields — is where you train your soldiers. Each field recruits a different type of troop. Level them evenly — there's no point in having one field very high and the others low, since you need a variety of troops for a balanced formation.

Bikers Camp

Bikers Camp

The Biker Field trains fast mobility troops. They're ideal for raiding and tactical movements on the map. Level it evenly with the other recruitment fields for a balanced formation.

Raiders Camp

Raiders Camp

The Assault Field trains your heaviest and most resistant troops. They're the backbone of any Rally attack and capital defense. Keep it at the same level as your other recruitment fields.

Hospital

Hospital

The Hospital recovers wounded troops after every battle. Without a high-level Hospital you'll permanently lose soldiers — it's one of the buildings you'll appreciate most once you start participating in alliance wars.

Inter-City Trade

Inter-City Trade

The Intercity Trade building lets you send trucks loaded with resources to other cities and earn rewards in return. A steady source of passive income — keep it active and collect regularly to maximize your resource flow.

Caravan

Caravan

The Radar unlocks the Hero Battlefield and special missions. It also expands your vision range on the map, helping you scout enemy bases and plan attacks more effectively.

Radar

Radar

The Radar expands your vision range on the map and speeds up enemy reconnaissance. Useful for scouting rival bases and planning attacks — not urgent early on but becomes more important in war seasons.

Task Center

Task Center

This building boosts your resource gathering efficiency across the board. Level it up to reduce the time and effort needed to collect materials from the map and keep your construction queues running.

Meeting Plaza

Meeting Plaza

The Meeting Plaza is essential for joining Rally attacks with your alliance. Without this building you can't participate in rallies — and rallies are the most effective way to take down strong targets.

Alliance Center

Alliance Center

The Alliance Center lets you receive troop reinforcements from alliance members when your base is under attack. The higher its level, the more allied troops you can shelter — crucial in active servers.

Warehouse

Warehouse

The Warehouse protects a portion of your resources when you're attacked. The higher its level, the more resources stay safe from looting. If you store a lot of resources without shields, this building can save your base.

Village

Village

The Villa expands both your population and total troop capacity. It directly complements the Residence — level them together so you never hit the soldier cap at the worst possible moment.

Library

Library

The Library unlocks and enhances your base's knowledge skills. These give passive bonuses to production, defense, and attack — over time they have a silent but very real impact on your total power.

Club

Club

The Club is where you recruit elite heroes and refugees with unique abilities. Keep it leveled to unlock better heroes and expand your refugee roster — some of the most powerful units come from here.

Vehicle Workshop

Taller

The Workshop lets you upgrade and modify vehicles to boost their combat power. As you progress into higher seasons, a well-upgraded vehicle can significantly increase your attack power in battle.

Centro de Control de Temperatura

Centro de Control de Temperatura

S3

Produces Lotus Flowers used to upgrade season-exclusive buildings. Essential during Season 3 — keep it leveled to unlock more powerful seasonal upgrades.

Laboratory

Laboratory

The Laboratory is one of the most important buildings in your entire base — and probably the one you'll need to level up the most. Every time you want to upgrade your HQ, you'll need a specific Laboratory level, so you have no choice but to keep it current. The research you unlock here is essential for everything: attack power, resource production, Alliance VS bonuses and much more. If you neglect the Laboratory, everything else stalls.

Laboratorio Biológico

Laboratorio Biológico

S3 - PRIORITY #1

Increases virus resistance and allows you to attack higher-tier Boomers that drop Ice Cores. A Season 3 priority — without this building you can't access the best resources of the season.

Glacial Military Depot

Glacial Military Depot

S3

Increases your troops' ATTACK during the season.

Glacial Fortress

Glacial Fortress

S3

Increases your troops' DEFENSE during the season.

Military Command

Military Command

S3

Increases your troops' DAMAGE during the season.
