- Sector 4 (AQA)
Although Yard were previously discovered on Zebes, Biological Science Labs obtained several specimens for study within the aquatic sector. When infected by the X Parasite, the strength of the Yard's shell increases tenfold, growing three large spines. The creature clings to the coral-encrusted walls of the sector and nestles in rocky crevices. The Yard-X uses these spines to focus energy stored within its shell, firing a hook-shaped plasma field at any non-infected creature that draws near.
The Yard-X has thick armor that can only be damaged by a fully-charged beam, and it takes two shots of a fully-charged Spazer to destroy them. You can also freeze them with an Ice Missile. The slow-moving plasma orbs will deal 33 damage normally, and can be hard to avoid if a room is full of enemies. Use Power Bombs to clear out the area quickly.
