Fargo's Mod/Guntera

Guntera is a secret that can be fought after all three mechanical bosses are defeated. It is only available with the Fargo's Soul Mod DLC installed.

Summoning
Guntera does not spawn on its own and must be summoned by the player by using while standing in front of Plantera's Bulb.

Attacks
Guntera follows a similar AI pattern to Plantera, but is armed with six guns attached to its main body (a Quad-Barrel Shotgun, Sniper Rifle, Uzi, Celebration Mk2, Venus Magnum, and Tactical Shotgun). These guns will all spray bullets at a very fast pace, each of which deals enough damage to instantly kill most players and inflicts a purely cosmetic debuff. The guns continuously spray bullets as they slowly rotate to aim at the player, but will occasionally reverse direction. The velocity of each bullet fired increases as Guntera's life decreases, and the bullets can pass through solid tiles for a short period after being fired.

Each gun has the same HP as Guntera but takes damage seperately from the main boss, and can be killed separately if desired. The guns will also despawn all projectiles on contact, making damaging Guntera through the wall of guns problematic.

At 50% HP, Guntera goes berserk, drastically increasing its movement speed and releasing a large number of hooks. Its hooks become extremely aggressive and lock onto the player at incredible speed, while also gaining the ability to latch onto air.

At 40% HP, Guntera's Hooks all create their own tentacles, which have the same HP as Guntera and also fire deluges of bullets dealing massive damage.

Guntera's attacks use multiple invulnerability cooldowns, meaning the player can be hit by attacks despite having invulnerability frames from taking another hit. This allows Guntera to deal its massive damage at an extremely high rate, especially in phase 2.

Trivia

 * While the boss is alive, the vanilla track Plantera will play.
