Call of Duty: Black Ops II
The Stealth Chopper functions in many ways to the Attack Helicopter in Call of Duty: Black Ops. When acquired, the user will pick where on the map the Stealth Chopper will initially be placed. When its point of hovering is picked, the Stealth Chopper is then summoned to that spot, where it will target enemy players and gun them down. It can move around in the airspace as it pleases. The Stealth Chopper will move around on its own in the airspace with time, so the initial placement of the Stealth Chopper in the airspace by the player isn't very important.
The biggest selling point to the Stealth Chopper is stealth. When summoned, only the announcer for the friendly team will announce the Stealth Chopper is incoming; the enemy team's announcer does not. However, there is one major exception to this: any and all Stealth Choppers acquired through Care Packages will have their presence announced to the enemies. The element of surprise means that enemies will very commonly not seek cover until the Stealth Chopper has attacked someone or they physically see or hear the Stealth Chopper in the airspace. The Stealth Chopper also does not appear on radar, and the Stealth Chopper overall is pretty quiet, with its rotors not being overly loud, and its machine gun being noticeably quieter than machine guns on scorestreaks like the Escort Drone or Warthog, although it is still very much audible.
Radio chatter will be heard when the player's own Stealth Chopper is active, as they will make callouts when seeing active targets, when they acquire kills, when they are being shot at, and when they are downed.
Much like the Attack Helicopter in Black Ops, each team can only have a maximum of one Stealth Chopper in the airspace. However, both teams can have a Stealth Chopper in the air, with the two Stealth Choppers not engaging with each other in any way.
The Stealth Chopper has one set of flares, which will be activated if a locked on rocket or a Black Hat is used against it. This means the Stelath Chopper will need two hits from locked on rockets and/or Black Hats to be destroyed. Although the Stealth Chopper has a fair amount of health, it will eventually be downed by bullets, with LMGs usually being able to down a Stealth Chopper with half of their belt/drum worth of fire. A weapon with FMJ equipped will be able to do especially high damage to a Stealth Chopper.
Like previous AI controlled aerial scorestreaks and killstreaks, the Stealth Chopper will prioritize attacking enemies that are actively attacking the Stealth Chopper. Enemies that are shooting the Stealth Chopper with bullets or launching locked-on rockets at the Chopper without Blind Eye will find the Stealth Chopper commonly shift focus to attacking them.
As the Stealth Chopper is an entirely AI controlled aerial scorestreak, it will not target enemies with the Blind Eye perk equipped, making these enemies virtually impossible for the Stealth Chopper to kill unless they get in the way of an enemy the Stealth Chopper is actively targeting.
The Stealth Chopper's AI is programmed to attack the closest player to itself. Meaning even if a far off player attacks the Stealth Chopper with a launcher or gun, the Stealth Chopper ignores them. This means it is easy for players without Blind Eye to easily shoot down the Stealth Chopper with a launcher or gun as long as they keep their distance. When the Stealth Chopper deflects an incoming missile with flares, the helicopter "jolts" to the side to evade the missile. This can make it harder for a player to line up a second successful shot with a lock-on launcher especially in cover or in a building. It is advised that the player pop out of the building or cover a small section just so they can achieve a lock onto the helicopter.
The pilot of the helicopter will talk to the player via radio. For example, he will say he is going down when the helicopter is being destroyed.
Call of Duty: Mobile
- "Call in an attacking helicopter to the battlefiled for armed support."
- — Description
The Stealth Chopper returns in Call of Duty: Mobile and functions similarly to Call of Duty: Black Ops II version. The Stealth Chopper doesn't deploy flares, it simply takes 2 rocket hits before being destroyed instead of one for the flares and one for a direct hit for lock on launchers.
- The Stealth Chopper does have pilots in the model, but they don't have detail.
