Spoilers ahead for bosses all the way to the end of the game Enter the Gungeon.
After that, you’ve got the option to finally make it to the floor with this boss.
This boss introduces the first boss in the Gungeon that requires a dodge roll.
Once his swarm is finished, he rests, exposing his heart which can be shot to damage him.
Along with these threats, the fight can be worse.
Once the boss hits its second phase, the fight really begins.
One special aspect to this fight is that it contains 4 separate bosses, being labeled as ancient heroes.
As the Pillars fall, the remaining gain new attack patterns and become harder to dodge.
When only one Pillar remains, they attempt to directly stomp the player and release bullet swarms on landing.
After firing these lasers, the ship will fire patterns of smaller bullets that are difficult to dodge through.
Along with many rockets, and just an overall barrage of fighting patterns to attack the Pilot.
This is the only boss capable of instantly killing you.
In this phase, Lich fires many bullets from his revolver and summons tombstone grunts.
This part of the fight is relatively easy and doesnt bother many people who fight it.
After finishing him off, he loses his bullet limbs and is immobile while panting from exhaustion.
Resourceful Rat
Finally, there is the Resourceful Rat.
First, over multiple runs the Gnawed Key must be bought, costing a total of 1000 casings.
Opening the trap with a key leads you to a long rail with nothing at the end.
This is all simply to make it to the fight, and then the fight starts.
This begins the most creative phase of a fight in this game.
This fight is unique because for once, you dont need to win to continue the run.
All the keys can only be used for Rat Chests or 2 other special locations.
