Blue Shift

Named after the Doppler Effect

It is the same as BulletDoubling (Old Wiki)

Example of waves that reach enemy at the same time

The picture to the right shows a group of waves clustered together.

How it Works

Fire a group of bullets that reach your target at the same time, either by moving the robot, changing bullet power, or a combination of both.

Concept

Use only on stationary targets (shows concept when farther away).
