Hover bots are enemies in Up Your Arsenal encountered in the Deep Sea Hideout, Aquatos during the mission "Infiltrate the underwater hideout". They are robotic soldiers consisting solely of a flying torso with their visible beneath a green glass visor, a jet engine in place of legs, a pair of arms, and a large canister on their back with the symbol for radioactivity. They wield a rifle in their right hand, which functions as a flamethrower. The flamethrowers are used either to launch a long-range blast from a distance, or to fire continuously in close range in a sweeping motion. The hover bots are hostile both to the amoeboids and to Ratchet and Clank.
The blast from the hover bots can deal considerable damage, requiring you to dodge them by strafe-jumping. They are also much tougher than amoeboids, and can sustain more damage. Due to their long-range, flight, and the fact that they do not cluster in the way amoeboids do, the N60 Storm and Spitting Hydra are the best weapons against them. Some of them will solely use their flamethrower up close, which makes them an easier target as long as you stay away.
As the hover bots prioritize amoeboids, it may be a good idea to let the two enemies battle one another and pick off the remnants, though doing so will miss out on experience for weapons.
