Swarm guardian

The swarm guardian is a zerg unit set to appear in StarCraft II.

Overview
The swarm guardian functions much like the original guardian as a siege unit, possessing a long range attack.

Their appearance has changed slightly, now looking more like a mutalisk laid out flat with its tail section behind it. Their bodies are made up of a total of five individual sections. The front section consists of the head and multiple appendages, maintaining the general appearance of the original crab-like guardian. There are three middle sections similar to the three rib-like claws that appear on the midsection of the mutalisk. Lastly a tail section which has four small spikes pointing backwards like those at the end of the mutalisk's tail. They move with a breaststroke-like swimming motion through the air. They are also much larger than their original counterparts, being only slightly smaller than a Battlecruiser.

Game Unit
The swarm guardian is similar to the original guardian, acting like a siege unit.

Spawning
When a swarm guardian attacks, it produces broodlings which lasted only a few seconds. The broodlings were very weak but a large number could be quickly created, forcing an enemy to retreat. They spawn when buildings are attacked as well.

Spawning Development
Every time a Swarm Guardian attacks, it used to spawn swarms, which could "soak up" damage.
