The KS-7 is a large spider platform — 2 meters at the thorax — that carries no weapons of its own. Instead, its bloated abdominal section contains twenty-four miniature spider drones, each the size of a human fist, which it deploys through ventral hatches. The miniatures are single-use antipersonnel units equipped with a shaped micro-charge and enough autonomy to navigate toward the nearest heat signature and detonate on contact. The KS-7 itself serves as a mobile deployment platform, navigating to a tactically advantageous position before birthing its payload.

The deployment sequence is the source of the platform's universally despised reputation. The KS-7 anchors itself to a wall or ceiling, its abdominal section distends visibly, and the miniature units emerge in rapid sequence — scuttling out from beneath the parent platform in a spreading wave that eyewitnesses consistently describe as 'hatching.' The miniatures move fast, are difficult to target individually due to their size, and the sheer number of simultaneous threats overwhelms human threat-processing capacity. Most targets freeze.

Arcturus marketing materials describe the KS-7 as a 'force multiplication platform enabling distributed engagement across complex terrain.' Combat veterans describe it as the worst thing they've ever seen come out of a laboratory. The miniature units have a functional lifespan of approximately four minutes after deployment, after which their batteries die and they become inert — but four minutes of two dozen fist-sized explosive spiders is an eternity.
