Redshift

In "Redshift", the speed of light is slower, so it takes longer for information to reach you. In this way you are counting down until you will see light generated in that same moment in global time. The closer you are the more immediate your perception is of an object, whereas they become further in the past the farther they are. Laser projectile colors redshift as they as are moving away, and blueshift as they are getting closer; an artifact of general relativity. You also count down until your projectile explodes, as it is on a timer you select with number keys. Direct laser hits kill you, whereas indirect explosion hits kill enemies.
