"After spending too long alone on the island, Sgt. Brick is ready to fight the Blackguard for real again."
Summary
Sgt. Brick is a Hero that aids you in battle with her abilities.
When you upgrade your Headquarters to level 4, you will have the ability to rebuild the Derelict Hut in the corner of your island. Doing so will unlock Sgt. Brick.
As a Hero, she does not require time or Gold to train. If she is defeated in battle, she will reappear in the Hero Hut after the battle, fully healed and ready to fight again.
In combat, she is a mid-ranged attacker who burst-fires at enemy targets, reloading after firing 15 rounds.
Her Hero Perk is Grenade Spammer, which causes her to fire a grenade every time she shoots at a new target to deal heavy damage.
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 Sgt. Brick. Click one to read more about it.
Although Brick can work as a supplementary damage source, she is relatively frail and generally superseded in that role by Everspark later on, due to having less range. Instead, she finds more success by supporting numerous smaller troops with Battle Orders to dramatically boost the attacking force' DPS. Notable examples include Laser Rangers and Zookas.
Brick should not be used with Tanks, as they tend to put her in the line of fire, and don't make much out of her bonuses with how much space they take.
Upgrade Differences
Each upgrade increases Sgt. Brick's hitpoints by 8%, DPS by 10% and Grenade damage by 8.2%; level 22 to 23's increments are slightly larger than these.
Trivia
Like with other Heroes, Sgt. Brick's death sound is not unique. In her case, she shares the same death sound with the Rifleman.
