EQUIP a covert Alarmbot. FIRE to deploy a bot that hunts down enemies that get in range. After reaching its target, the bot explodes and applies Vulnerable to enemies in the area. HOLD EQUIP to recall a deployed bot.
— In-game description

Alarmbot is a basic ability for Killjoy.


Alarmbot is primarily an Intel ability that Killjoy must equip before casting. Once equipped, her crosshair will be replaced with an indicator for placing a bot. This will turn pink if it is placed on a viable position to be cast in, and will turn red for unviable positions. Upon casting, the bot will briefly deploy at the location before turning invisible. The bot can be recalled but will go on a short cooldown before it can be redeployed. Once deployed, the bot remains indefinitely. For it to remain active however, Killjoy must remain within a certain distance from the bot. Exceeding this distance will cause the bot to deactivate, becoming visible and not responding to any enemy agents that pass by it. Reentering the proximity range will reactivate the bot. The bot will also deactivate if Killjoy is killed or suppressed.

Enemy agents who approach it will be able to see it once they get within close enough proximity. Enemies can deal damage to the bot and destroy it, though Killjoy and her team will be alerted if the bot is destroyed.

If an enemy agent gets too close to the bot it will activate in three phases. First it will become alert, revealing itself to enemies. It will then travel from its location towards its target. If it is able to get into closer proximity to the target without being destroyed, it will then jump up and explode, applying Vulnerable to any agents in range.
