Introduction

Spanning across six phases, each lasting four hours, participants earn points through various actions, unlocking chests as they progress.

The event’s difficulty scales with the level of your headquarters, ensuring a challenging experience tailored to your progression.

Rewards

Each phase allows you to obtain different rewards:

• Current phase chests (The large red/blue/orange chests)
  

  

• Today’s goal chests (Smallest bronze/silver/gold chests)
  
• Overall daily ranking rewards

Current phase rewards

As you score points, the progress bar will fill green, gradually allowing you to open large chests (red/blue/orange) that have various rewards.

The most important prize of these chests are the Arms Race Badge , in fact these badges contribute to the opening of today’s goal chests

Arms Race Badge can always be found in chests in this quantity:

• First chest: 1 Arms Race Badge
• Second chest: 2 Arms Race Badge
• Third chest: 3 Arms Race Badge

Opening chests of today’s goal

Every time you open a chest you get an Arms Race Badge as described in the previous paragraph.

Once you reach 2 / 8 / 18 Arms Race Badge, the bronze/silver/gold chests containing very important prizes are opened:

Overall daily ranking rewards

Finally there are the rewards for the daily general ranking.

Phases

You can check the schedule of the phases clicking on the upper left calendar icon inside the the Arms Race Event page.

The time can change from day to day but the order of the phases is always the same:

City Building

This phase focuses on expanding the base, meaning leveling up your buildings.

• Increases Building power by 1 point:
  Every time a construction is completed, that construction will have increased its power and points are obtained for this difference. Note that the building’s strength increase only occurs when you open the gift box in which the newly upgraded building is packaged, only in that moment the points are rewarded.
  Tip : during the day when you have completed upgrading a building, if you do not need to access its functions, leave it packaged and then open it during this phase to obtain the relevant points. See image above
• Use 1-min Construction Speedup :
  Use Speedups
  (construct speedup or generic speedup, any length).
  Points are rewarded immediately as the speedup is used.

Unit Progression

This phase focuses on unit (troops) progression. Train soldier here refers to both training them from scratch and upgrading them from one level to a higher level.

• Train a Lv. 1/2/3/4/5/6/7/8/9/10 unit :
  Points are given based on a soldier’s arrival level. So upgrading a lvl 4 to a lvl 5 gives you the points of a lvl 5 in the same way as training a lvl 5 from scratch. So prepare many intermediate level soldiers to upgrade as an assembly line. See the Troops guide for how to upgrade a soldier.
• Use 1-min Training Speedup :
  Use Speedups
  (training speedup or generic speedup, any length).
  Points are rewarded immediately as the speedup is used.

Tech Research

This phase focuses on carrying out researches in the technology center.

• Increases Tech Power by 1 point :
  When a research is completed in the Technological Center, technological power points are rewarded.
• Use 1-min Research Speedup :
  Use Speed ups
  (science speedup or generic speedup, any length).
  Points are rewarded immediately as the speedup is used.

Drone Boost

• Use 10 Drone Combat Data points :
  Go to the  Drone Center and click the Data Training  button to use battle data. At certain levels it is necessary to have drone parts in order to proceed with training.
• Use 1 Stamina:
  Use stamina to: attack zombies/bases, execute rallies towards zombies/bases, complete radar missions.

Hero Advancement

• Elite Recruit 1 time :
  Use the Legendary Recruitment Tickets in the heroes section, “Recruit Heroes” button -> “Recruit Heroes”
  Season 1 Upgrade:
  Use the Hero’s Return Recruitment Tickets in the heroes section, “Recruit Heroes” button -> “S1 Hero’s Return”
• Use at least 2000 Hero EXP at a time :
  Use EXP (experience) points, i.e. use the “Upgrade” button after selecting a hero

Strategy

Arms race rewards are critical to grow at any stage. To secure all the prizes you need to organize the actions you do during the day well.

Some of these associations are obvious, others less so, below is a summary table of what to do and at which stage:

Area	Action	Arms Race Phase
Buildings	Level up	City Building
Troops/Soldiers	Training, updating	Unit Progression
Technology Center	Complete searches	Tech Research
Drone	Use of drone combat points	Drone Boost
Heroes	EXP Boost, Recruit Heroes	Hero Advancement
Tavern	Recruit Heroes	Hero Advancement
Radar	Perform mission by consuming stamina	Drone Boost
Attacks/Rally	Stamina consumption	Drone Boost

The following actions do not contribute points in any Arms race phase (but they will during the VS duel event which is available later), so they can be done at any time without losing points:

• Heroes: Raise class, use skill medals to upgrade skills
• Drones: Synthesize drone components
