Account & Server Basics

Account Binding Rules

The game offers four official login options: Device Login, IGG Account, Google Account and Facebook Account.

Device Login is strongly not recommended. Accounts created via this method are locked to a single device permanently. You will not be able to switch your game progress across phones, tablets, computers or other devices. For long-term play and flexible device switching, bind your account to an IGG, Google or Facebook profile right after registration. This ensures your game data is safe and accessible anywhere.

Server Types & Version Mechanism

Servers are divided into two main versions: Series A (old version) and Series B (new version). While the interface layout differs slightly, core gameplay, hero attributes and troop systems remain identical across both versions.

All servers are grouped into five major combat zones: East Zone, South Zone, Southwest Zone, North Zone and West Zone. Players are free to select and travel between servers from different zones.

Every server runs on a two-phase cycle: a 90-day Construction Period, followed by a 90-day Semi-Open Period. Cross-server migration rules vary greatly between these two phases, so be sure to check the server status before moving.

Mandatory Server Migration Rules

Many players want to switch servers to team up with friends or alliance members. Before using the migration function, you must meet all system requirements, otherwise the migration will be denied.

Step-by-Step Server Migration Guide

1. Fully zoom out the main game map and tap the globe icon to open the server list.

2. Select your target combat zone and target server.

3. Read the migration requirements carefully and confirm you satisfy all conditions.

Full Migration Restrictions

• All construction, research and troop training queues must be idle.
• Your base and squads cannot be engaged in any battles.
• Your account cannot hold the alliance leader position.
• Total carried resources cannot exceed your warehouse protection capacity.
• Key Restriction during Construction Period: If the target server is in its Construction Period, accounts with a Headquarters level of 10 or above are forbidden to migrate in. This is the most common reason for migration failure for new players.
• After successful migration: Some event points will be cleared; your base will spawn at a random location on the new server; the game client will restart automatically.

If you see a prompt stating you do not meet immigration criteria, double-check your Headquarters level first — this is the top cause of migration issues for new players.

 

Standard Growth Stages

The entire account growth cycle is divided into three standardized stages, applicable to all players regardless of spending levels, serving as the core benchmark for early, mid, and late-game development.

Early Game (T1–T4 Troops)

The core goal of the early game is to build a complete basic account framework. Players need to lock a single troop development route, accumulate sufficient basic resources and speed-up items, and lay a solid foundation for mid and late-game advancement.

Mid Game (T5 Troop Unlock)

After unlocking T5 troops, players enter the shaping stage. The core tasks include awakening core hero pairs, upgrading key buildings to level 25, and confirming a fixed PVP development positioning for the account.

Late Game (T6 Troop Unlock)

The late game is the mature stage of account development. Players focus on refined equipment cultivation, full combat power breakthroughs, and proficiently mastering all high-end PVP gameplay to maximize event rewards.

 

Early-Game Infrastructure & Building Priority

Headquarters (HQ) Leveling Rule

The Headquarters level locks all core game progress, including troop tiers, hero capacity, and advanced building unlocks. New players only need to upgrade mandatory buildings required for HQ advancement, and do not need to max out all auxiliary buildings simultaneously to avoid unnecessary resource waste.

Core Mandatory Buildings for High-Tier Troops

• Lookout Tower: Consumes Outpost Toolboxes mainly dropped from zombie events. It is a mandatory prerequisite for upgrading the Battle Center.
• Battle Center: Upgraded with Victory Badges. It determines the maximum rally squad size and is the key building for unlocking T6 troops.
• Research Lab: Level 25 Research Lab is the core threshold for T6 troop technology research and mid-to-late game combat power improvement.

Standard Item & Resource Usage Rules

• Speed-Up Items: Do not use speed-ups blindly. Always receive the maximum 30 alliance assists first to reduce construction and research time, then use speed-up items to achieve the highest resource utilization efficiency.

• Resource Reserve: Stockpile crude oil sufficiently in the early game. T6 troops consume a massive amount of crude oil, making it an indispensable core resource for late-game development.

 

VIP Level & Gem Allocation Standards

Must-Reach VIP Level Milestones

These key VIP levels provide permanent, game-changing benefits for all player types. Reaching these milestones in order is the core priority for long-term account growth.

VIP Level	Core Permanent Benefits	Player Goal Positioning
VIP 6	Unlocks the second permanent construction queue; paired with monthly passes to activate three build queues, drastically speeding up early-game base and infrastructure progression.	Basic early-game milestone for all new players
VIP 9	Unlocks daily free golden puzzle gameplay, offering stable long-term outputs of hero fragments and basic development resources.	Stable resource milestone for mid-term growth
VIP 13	Grants daily fixed legendary hero fragments, the most reliable long-term source of core hero awakening materials in the game.	Core end-game milestone for F2P & low-spend players
VIP 14	Further optimizes gem consumption efficiency and resource acquisition limits.	Ultimate milestone for medium-spend players
VIP 17 / 18	Unlocks top-tier exclusive bonuses including squad travel speed, full advanced attribute buffs, and ultimate cultivation privileges.	End-game pursuit for high-spend and whale players

 

Universal Gem Spending Priority (Pure Benefit-Based)

This standardized spending sequence eliminates subjective preference and maximizes long-term account growth benefits.

• Prioritize upgrading VIP levels to reach predefined key milestones.
• Concentrate gem consumption during Gem Rebate Events to obtain exclusive legendary hero fragment rewards.
• Use gems on Lucky Roulette for functional hero unlocking and fragment acquisition.
• Purchase all types of speed-up items from the VIP store.
• Spend gems during overlapping events such as Alliance League and Bloody Brandy to stack bonus benefits.
• Use surplus late-game gems to supplement legendary hero fragments and high-level equipment materials.

 

Standard Troop Cultivation System

Core Troop Mechanic

Troop tier outweighs troop quantity in all combat scenarios. A small number of high-tier troops can easily defeat a large army of low-tier troops, making tier upgrading the top priority for combat improvement.

Stage-Based Troop Development Rules

• Early Game: Adopt single-troop specialization. Choose one route among Infantry, Ranger, or Rider, and match with corresponding core heroes to avoid scattered resource investment.
• Mid Game: After the main troop reaches T5, gradually develop other troop types to improve squad flexibility and rally adaptability.
• Late Game: Fully max out the main T6 troop. High-spend players can expand development to unlock full T6 troop types for all classes.

Fixed Troop & Main Hero Matching

• Infantry Main: Rubina
• Rider Main: Felix
• Ranger Main: Julia

 

Complete Hero Cultivation Guide

Early-Game Transition Heroes

These heroes have stable fragment sources from daily and weekly tasks, requiring no extra investment, making them the best transition choices for new players.

• Core transition heroes: Liam, Charlie, Peggy, Jaden
• Standard Charlie skill activation order: 1-3-2-4

Mid-Game Core Legendary Heroes

• Functional Support Hero: Tom, providing team damage reduction and essential for all mid and late-game team battles.
• Three Major Legendary Main Heroes: Corresponding to Infantry, Ranger, and Rider, serving as the final core hero lineup for account graduation.

Universal Hero Cultivation Rules

• Early Game: Focus resources on cultivating 3 transition heroes only; avoid average and scattered development of multiple heroes.
• Mid & Late Game: Replace transition heroes with troop-specific legendary heroes, and prioritize awakening two core hero pairs.
• General Principle: All hero cultivation resources are tilted to main heroes exclusively; average cultivation is prohibited.

 

Full-Cycle Event Participation Rules

Daily Mandatory Events (Fixed Resource Output)

Complete these daily events steadily to accumulate basic resources for long-term growth: Z-Virus Adventure, Memory Lane, Radar Station Recruitment, Police Station Free Recruitment, Scout Exploration, Beast Trapping, and Workshop Production.

Weekly & Monthly Regular Events

Participate in all cyclic server events to obtain advanced materials and exclusive rewards: Bounty Ground, Alliance Centipede Battle, Pompeii Recovery, Alliance League, Genesis War, Island Raid, and Archipelago Raid.

Top Commander Official Mechanisms

Top Commander is the core high-reward multi-stage event for hero fragments and advanced items, with fixed system rules for all players.

• The event lasts multiple days with independent scoring themes and scoring rules for each phase.
• Hard score caps apply: Speed-up scoring and vehicle scoring are capped at 100 million points per single day.
• Arrow items must be accumulated to 1000 pieces before participation; scattered use yields no ranking rewards and causes resource waste.
• Standard gameplay: Reserve sufficient resources in advance and put in items accurately according to the daily event theme.

 

Equipment & Beast System Standards

Armament & Equipment Cultivation Rules

• Universal Rule: Focus all equipment resources on one main hero. Dismantle idle and redundant equipment to exchange for core cultivation fragments.
• Stage Goals: Early-game target is full 5-star purple equipment; mid-game target is full 5-star golden equipment; late-game end goal is red-tier and white-tier top-tier equipment.

Core Beast System Mechanism

• Core Logic: Beast synergy and skill linkage are far more important than elemental attribute restraint. Matching main and assistant beasts can trigger multiple damage multiplier effects.
• Early-Game Standard: Prioritize building linkage beast combinations, no need to pursue high single-beast attribute stats.

 

Alliance System Rules for New Players

Basic New Player Alliance Rules

• Join a high-activity alliance immediately after starting a new account to obtain construction assists, base territory protection, and exclusive alliance event rewards.
• Complete base garrison configuration within 48 hours to avoid group alliance risks.
• Reach VIP 6 and participate in alliance rally activities within the first week of gameplay.

Standard Alliance Collaboration Mechanism

• Unify troop development division among alliance members to avoid homogeneous troop waste.
• Coordinate hero lineups within the alliance to achieve functional complementarity and repeated configuration avoidance.

 

Stage-Based Graduation Standards

Early Game Graduation Standard

Complete single troop specialization, full transition hero cultivation, unlock core VIP 6–VIP 9 benefits, upgrade basic infrastructure to match current stage, and reserve sufficient early and mid-game resources.

Mid Game Graduation Standard

Fully awaken two core hero pairs, max out Lookout Tower, Battle Center and Research Lab to level 25, form stable T5 troop combat power, and confirm clear PVP positioning (field combat, garrison, or rally).

Late Game Graduation Standard

Unlock and mature main T6 troops, complete high-tier equipment refinement, master all end-game PVP gameplay, and reach the standard combat power corresponding to the player’s spending tier.
