The Spitting Hydra is a weapon manufactured by Gadgetron in Up Your Arsenal. It is an electric weapon which locks onto targets as it is held down before unleashing tendrils of electricity that damages them.
The Spitting Hydra is made available upon reaching Marcadia for 40,000 bolts. It is required for the challenge Hydra'n Seek in Annihilation Nation. With use, the Spitting Hydra can be upgraded to the Tempest, which in challenge mode, can be upgraded to the Mega Tempest for 540,000 bolts.
The Spitting Hydra is a light blue and silver carbine with a large nozzle and a left-handed grip. When being charged up, it makes a humming noise before it unleashes multiple large tendrils of lightning that hit the targeted enemies. The Tempest is a purple, silver and blue weapon with a much larger nozzle that dishes out more lightning tendrils.
The Spitting Hydra locks onto targets while the fire button is held down, before it is released, causing the weapon to shoot out tendrils of lightning. While they damage the enemies that it locked onto, they also damage any enemies which get caught into the lightning tendrils. Therefore, the player should maximise ammo by firing from an angle that not only hits the maximum number of enemies, but will catch smaller enemies in with it.
The Spitting Hydra is most effective against mobs of smaller enemies when used correctly, though it is most potent against groups medium sized enemies. Against single enemies, the Spitting Hydra is weak, making it ineffective against bosses. The Spitting Hydra and its upgrades are also rapidly outclassed later on, particularly by weapons such as the Annihilator and the Plasma Coil.
The Spitting Hydra's upgrades not only add damage, but allow it to target more enemies. At V1, it can lock onto three enemies at once. This increases to four at V2, five at V3, six at V4, and seven as the Tempest. The upgrades to the Spitting Hydra do not address its weakness against smaller groups of enemies or bosses, and the number of enemies it can lock onto becomes redundant later on.
