The tank has three general types, Attacker (ATK), Defender (DEF), and Speedster (SPD). The ATK is where all the damage colored by red, they usually has normal HP and high damage. Defender is where it has at least one damage colored by blue while the other is red. DEF will have the highest HP but a low damage. The last is the SPD. SPD will have at least two blue damage bar. This blue damage bar means the first strike (The tutorial of the game will explain this, but I will try to explain this later). SPD will have pretty high damage but low HP.
At the arena, we will try to decide which ability that we want to trigger in that round. Action Point that used for triggering the ability will always be replenished each round, so make sure you use the action point wisely.
Afterwards the war will begin with decision on who will strike first. This where the blue bar damage counts. The one who will strike first is the one that has the highest total blue damage on their tank. If the value the same or no tank gets any blue damage, the first strike will be decided by coin tossing.
Aside from the arena, this game also has some interesting component inside. We can build tanks with tank parts that we can gather during the arena, or can be claimed by opening the contracts. There also collections mode in this game. It means that after we build certain set of tank, we will get a reward.
Besides unlocking tanks, we can also unlock more abilities. The only requirement needed is we climbed through the rank. Bronze, Silver, Gold, Ruby, and the ultimate rank is Diamond. Every time we win the arena, we will get the so-called League Point. After certain League Point gained, we will have opportunity to be promoted in the next rank. We just need to win 3 times and avoid losing 3 times during that promotion chance.
