The LS-5 is a corporate lobby security platform — a tall, cylindrical unit standing 2.3 meters with a rotating sensor head and two retractable arm assemblies concealed within its chassis. In standby mode, it resembles a decorative column, finished in brushed steel or custom corporate livery. Arcturus deliberately designed it to look architectural — something you might walk past in a lobby without registering it as a machine. This is intentional. The LS-5 is meant to be discovered only when it activates, and by then it has already scanned, assessed, and targeted.

When triggered, the LS-5's transformation is fast and startling. The arm assemblies deploy in 0.8 seconds — one carrying a focused sonic projector capable of disorienting targets at 20-meter range, the other carrying a kinetic restraint launcher that fires a weighted bolas designed to entangle limbs. The sensor head exposes a full threat-assessment suite that had been passively scanning through the unit's decorative exterior the entire time. The LS-5 was watching before you knew it was there.

Arcturus markets the LS-5 to corporations that want visible security without visible security — buildings where armed guards would undermine the corporate aesthetic but where the threat of intrusion is real. The LS-5 provides deterrence through ambush rather than presence. You don't see it. You don't know it's there. Then you do something you shouldn't, and a column deploys weapons at you.
