The Zodiac was an extremely powerful weapon created by Megacorp. It was available for a hefty 1,500,000 bolts and fired a charge of lightning that franticly decimated all enemies within range. However, the weapon had some depreciating downsides. It had four ammo slots and the ammunition cost 10,000 bolts each, yet ammo for the weapon could be found in Ammo crates. It was useful against swarms of enemies, but it wasn't effective against bosses. If any single enemy moved out of Ratchet's line of vision, it would be unaffected. It had no upgrade and, along with the Mega Mini-Nuke, was one of the most expensive weapons in the game.
- The Zodiac was more specifically called the Zodiac Mk.II. This is because the original "Zodiac" weapon was in Insomniac's first game, Disruptor. This Zodiac also wiped out enemies within sight.
- The RYNOCIRATOR in Ratchet & Clank: Up Your Arsenal had the same effect as the Zodiac.
- The achievement BFG (blast frequency gun) is a reference to a game by capcom, Dead Rising 2, due to the fact that there is a weapon, called the BFG, that has similar effects to the zodiac. (sorta)
- The Zodiac also increases the number of bolts Ratchet can obtain when destroying enemies, depending on his boltiplier.
- If you use the Zodiac while moving, sometimes the weapon firing animation is not shown.
