Gunstar Heroes/Weapons and upgrades

One of the defining aspects of Gunstar Heroes is the ability to combine two of the four starting weapons into better weapons.

Starting Weapons

 * Force — Rapidly fires a stream of bullets.
 * Lighting — Fires a laser that penetrates enemies and walls.
 * Chaser — Fires bullets that home in on an enemy.
 * Fire — Fires a short-ranged, but powerful, stream of fire.
