The Guide 2.0

About
The Guide is the hardest boss in the game. He's quick, deals a lot of damage, and has the largest health pool out of all the bosses in the game.

Behavior
Normal Mode: This boss has 4 stages.

Stage one: He stays in the center of the screen and spins frantically and sprays volleys of sniper bullets that are extremely fast. He persists this way until he drops below 5000 health, then he initiates stage two.

Stage 2: The boss will slowly circle around the center of the arena in a large circle and fill the entire screen with very slow, very high damage bullets. He continues this way until he drops below 3000 health. At which point he will start his third stage.

Stage 3: The boss quickly moves back and forth along the top of the arena shooting a spread of three high damage bullets at the player. He will do this until he drops below 1000 health, and when he does stage four, the final stage, begins.

Stage 4: As soon as stage four begins the boss rushes to the top center of the screen and creates a bubble of protection around himself and begin to continue his stage one attacks for 1000 frames. As soon as these 1000 frames are up he becomes exhausted, lowers his shield, and slowly rotates until he is killed. Once he dies, the game is over and the player is redirected to the win screen.

Strategy
The best strategy to defeat this boss is basically just to stay as far away from it as possible to give his bullets time to spread out so you can slide in between, making Mantis a very poor choice for this boss. Sawney is also a poor choice since you have to make very small movements to dodge attacks and Sawney won't shoot unless you maintain a steady pace. Note that Crimson's pool of blood and Redd's death laser can be used to damage the boss while he's immortal.
