Ospreys are flying robotic units used by the Corpus. Relatively fragile, they provide support with buffs and debuffs instead of blunt firepower. The Ospreys' ability to hover makes them difficult to strike with melee attacks.
Identified by their light green bodies, Leech Ospreys deploy small mechanical parasites that drain players' shields. Although the leeches cannot kill players themselves, they can leave the player vulnerable to Corpus attacks. Leeches can be removed with a melee attack or by rolling. While the leeches will home in on targets, they are still avoidable by making them fly into walls, which will stop them.
Yellow-orange Mine Ospreys deploy energy orbs that will explode after a short period of time, or if a player steps on them. They will continue to deploy mines as long as there are players nearby. It is possible for mines to attach themselves to other units if they land on them and potentially killing them. Mines can also be destroyed by shooting them before the osprey deploys them.
The Oxium Osprey is a Corpus Osprey introduced in the Operation: Oxium Espionage event. Although armed with a laser repeater similar to those equipped on Scavenger Drones, its primary means of attack involves charging at players once it takes damage, detonating itself if it gets close enough to them. As their name suggests, they are the only enemies in the game that drop Oxium{"Type":"Resource","Description":"Oxium is a rare lighter than air alloy of Orokin origin, used in certain Corpus Robotics.\r\n\r\nLocations: Venus, Jupiter, Mars, Neptune, Pluto, Eris, Europa, and Lua.","Link":"Oxium","HelminthCategory":"Oxides","HelminthGain":"0.3","Image":"Oxium.png","Name":"Oxium","Amount":["7","12"],"Introduced":"11.9","InternalName":"/Lotus/Types/Items/MiscItems/OxiumAlloy","HelminthCost":"750"} (7-12 units per Osprey) but only if they were destroyed by the player; they do not drop Oxium if they self-destruct.
Sapping Ospreys are Corpus Ospreys that deploy an orb which generates an AoE damage field. The orb releases pulses of damage over several seconds, then floats approximately 2 meters into the air for a final detonation.
Remech Ospreys only appear in Ambulas missions to repair disabled Ambulas. If they succeed the Ambulas is unhacked again and will continue to attack players (if repaired Ambulas is captured by the dropship it will count towards failure counter).
AttackDrones are deployed by Fusion MOAs when they reach about 50% health, but can be avoided if you destroy the MOA during its short deploying period.
Due to their fast-firing weapon, hovering nature, and immunity to crowd control status (e.g.: ragdoll, stun), they pose a big threat.
Scavenger Drones appear as large yellow-green Ospreys. Aside from being able to fire lasers akin to the Fusion Drone (though with less damage), these drones are able to vacuum up dropped items nearby such as ammo or materials, and then release a bright-yellow Rippling Shockwave thereafter. Destroying this Osprey will not always drop loot that was confiscated.
