## Description
In _GunRun_ the player does exactly what the title implies, gunning things
down while running. The player must shoot the robots on screen either flying
or travelling on the ground with their machine gun. The objective is to kill
enemies and collect as much “$” as possible to get points. To do this the
player must gun down the ever increasing number, power, and speed of the
enemies. If they run in to the enemy or hit by its bullets, they will lose a
life.
The player controls the character on screen by the “A” and “D” keys and jumps
(or double jumps) with ether the space bar or “W” key. The gun is controlled
by the mouse by simply clicking on where the player wants to shoot up to the
maximum 45 degree angle. The screen scrolls along at a constant pace to always
keep the player in the action. At set points the game will advance a level
and, without stopping the action, will introduce more powerful enemy or
enemies. Occasionally a bonus level with “$” but no enemies will give the
player a rest however, this is made up by the boss once every 20 levels. To
help the player there are several power-ups like Life (collect 3 to increase
the max life), Gun power-ups (collect 5 to add a level to the gun), Star
(clears the screen of enemies), Invincibility (for a limited time), and Rage
(Invincibility, super powerful machine gun, and a level speed up for a limited
time) that can be collected by grabbing them as they appear on screen. There
is no end to the game; the player just plays till death.
