Leech Gun

A powerful and versatile weapon. Ammo is gained by using the secondary fire to draw energy from nodes found throughout the Sphere. Different nodes make the gun take on different properties:
 * Plasma (red glow): fires fast-moving balls of energy causing moderate damage;
 * Freeze (light-blue glow): short-range attack which turns enemies into ice;
 * Lightning (white sparks): fires a bolt of electricity — one or two shots kill most enemies, but "ammo" is more limited than with other types;
 * Sunbeam (orange glow): a violently incandescent beam which cuts down most enemies almost instantly, as well as pushing the player back while firing.
