"It's not quite clear why Private Bullit has never been promoted, but it might have something to do with his attitude."
Summary
Pvt. Bullit is a Hero that supports your troops with his abilities.
To unlock him, you need to defeat Lt. Hammerman's level 55 HQ, which is unlocked at Level 19 Radar as well as 117 map regions revealed.
As a Hero, he does not require time or Gold to train. If he is defeated in battle, he will reappear in the Hero Hut after the battle, fully healed and ready to fight again.
In battle, he is a short-ranged attacker with very high hitpoints and very high damage per second.
His Hero Perk is Pain Tolerance, which limits the maximum amount of damage dealt to him in a single hit.
Pvt. Bullit’s attack frequency increases as he takes damage.
When he has at least 75% of his hitpoints, his attack frequency is 1 second.
When his hitpoints are between 50% and 75%, his attack frequency is approximately 0.825 seconds.
When his hitpoints are between 25% and 50%, his attack frequency is approximately 0.75 seconds.
When he has less than 25% of his hitpoints, his attack frequency is approximately 0.625 seconds.
Hero Abilities
Similar to Gunboat Weaponry, Hero Abilities can be used during battle at the cost of Gunboat energy. Your hero can only have one ability active in a battle. The ability can be fired more than once, but the energy cost increases each time. The following are the three abilities available to Pvt. Bullit. Click one to read more about it.
With his Pain Tolerance Hero Perk, he has incredible survivability against high damage single-shot defenses. You can use his Taunt ability to protect other troops such as Heavies, Tanks, Scorchers, and Mechs from high-damage defenses and even outright negate the Doom Cannon's attacks.
His main weakness comes from fast-firing defenses such as the Machine Gun and Shock Blaster. These defenses can do sufficiently high damage per second while doing damage per shot that is low enough such that his Hero Perk does trigger. Destroying these defenses or avoiding them entirely when using him will thus be beneficial.
Upgrade Differences
There are no visual differences, but each upgrade increases his hitpoints (by 8%), damage per second (by 10%), and reduces the damage limit on his Pain Tolerance (by 100).
Trivia
He has the highest hitpoints and DPS of all Heroes.
'Private' is the lowest military rank, and also the lowest known rank in the game.
Contrary to the game's description, he has been promoted several times, though each time he celebrated by doing something that ended up demoting him.
If you look closely, Bullit already has an Energy Drink bottle attached to his belt, but oddly, he still needs Gunboat energy to use it and still has it even when using other abilities.
Pvt. Bullit shares many similarities with Bull from Brawl Stars, another SuperCell game. Both are very tanky, both wield triple barreled shotguns, both are short ranged, both have bull themed belt buckles and both have the ability to increase their fire rate when low on health.
