Stats

Stats are upgraded by Skill Points. It costs one skill point per upgrade. The upgrades give a smaller boost the more you buy.

You can buy Body Damage, Max Health, Bullet Speed, Bullet Health, Bullet Penetration, Bullet Damage, Reload, Movement Speed, Shield Regeneration, and Shield Capacity.

Body Damage
The Body Damage stat increases damage dealt when in contact with another entity with health (e.g. Tank, Polygon, Crasher, etc.). This is mainly used in the Ramming build.

Max Health
The Max Health stat increases maximum health. This is also commonly used in Ramming tanks.

Bullet Speed
The Bullet Speed stat increases bullet speed. This might lower the bullet damage by a bit, as the bullet takes less time to pass through the enemy player, lowering the amount of damage dealt. Because bullets still take the same time to disappear, this also increases the bullet range. This is most useful in Sniper-class tanks and Pounder-class tanks.

Bullet Health
The Bullet Health stat increases bullet health. This allows the bullet to receive more damage when penetrating a polygon, player, or crasher. This is most useful in bullet spammers.

Bullet Penetration
The Bullet Penetration stat increases bullet penetration. This allows the bullet to deal more damage when penetrating a polygon, player, or crasher. This synergies well with Bullet Health, and is most useful in bullet spammers.

Bullet Damage
The Bullet Damage increases the damage your bullet inflicts to shapes, crashers, bosses, and players. This is useful for all tanks, because you will deal almost zero damage otherwise.

Reload
The Reload increases the rate of fire of bullet tanks, respawn rate of minions and drones. For tanks with no barrels (Smasher branch), this turns into acceleration.

Movement Speed
The Movement Speed increases your movement speed. This is recommended for rammers.
