The Cyclone is a fast hit-and-away vehicle produced from the Factory. It was first introduced in Legacy of the Void.
The Cyclone has a high spell damage ability (Ignores Armor completely) called Lock-On that is ideal against aerial, high health and/or slower moving targets. In the early game this unit is often seen defending alongside Missile Turrets and Marines, and later on raiding undefended opposing mining workers and bases with Hellions.
Locks the Cyclone's weapons on the target air unit, dealing 160 damage over 14 seconds to Flying targets. Can move while firing. Cancels if target moves out of range or vision.
To use the Lock On ability, a Cyclone must move within 7 range of a target. Once Lock On is activated, a Cyclone can move away from the target for up to 15 range while still maintaining effect. Lock On lasts for 14 seconds after activation, but the effect is broken if target moves out of vision or exceeds the maximum 15 range.
Lock On is an ability and therefore ignores the armor of a targeted unit. This is important to note against high armor units like the Battlecruiser and the Carrier.
Rapid Fire Launchers
Improves the Lock On ability to fire the first 12 shots quickly.
- Against Banshee openings, this unit does not win in 1v1 fights and needs to be micro'd away to keep out of the Banshee's firing range.
- Against early Marines + Siege Tank pushes common in this mirror match, Cyclones do little except spot the attack coming across the map. Mass Hellions to kill the Marines (leaving the Tanks defenseless) is far more useful.

- How about I make this really simple. You point them out, then I risk my neck by driving right up to them. Then, get this, I kill them! Sound good?
- Okay, so this is you, "Hey, Cyclone. What you're doing?"" Then I'm like, "Nothing, I just want to go kill things!"
- "Well how 'bout we have a nice long talk instead?" "Gee, I dunno, boss. That sounds pretty awful. Maybe we could just stop this whole thing and get back to shooting stuff!"
- "No, I'm just going to keep on doing it. Blah bla-blah bla-blah. Poke poke poke!"
- [sigh] (to self) Don't let 'em get to you, man... just pushing your buttons.
- Will you quit doing that!?!
- Moving into position.
- Nothing'll stop me.
