Escape Ship is the final boss in Gradius: The Interstellar Assault.

Attack patterns

The Escape Ship has two phases, the first is the chase and the second is after it's engine is damaged.

In the first phase, it attempts to destroy you by flying through wreckage of a fleet (most likely yours) while releasing indestructible mines behind it.

In the second phase, the Escape Ship attacks by firing 2-4 Missiles and a Vector Laser if the ship goes directly in the line of sight of the engine.

It is not a very hard boss once the pattern is found.
