Zyrex Threat Bestiary & Colony Hazards Database

The Wall is infested with aggressive biomechanical organisms known collectively as the Zyrex. Understand their assault angles, targeting behaviors, and tactical vulnerabilities before they breach your life support systems.

Confirmed Zyrex Swarm Units

Hostile Organisms

Threat: Low Wall Crawler

Zyrex Skitterer (Scout)

Fast, multi-legged biomechanical scouts that climb vertical masonry at breakneck speeds. They probe colony perimeters for unfortified scaffolding and open vents.

Armor Class: Unarmored

Primary Target Priority: Power lines, open ventilation shafts, lone miners

Tactical Counter: Kinetic Flak Cannons set to broad sweep; light perimeter electric fences.

Threat: Medium Wall Crawler

Stalker Swarmer

The standard infantry unit of the Zyrex horde. Attacks in coordinated waves of 15 to 40 creatures, swarming across outer scaffolding and tearing through outer airlocks.

Armor Class: Light Chitin

Primary Target Priority: Habitation capsules, exterior stairwells, worker convoys

Tactical Counter: Overlapping flak fire grids; choke points protected by EMP Resonance Disrupters.

Threat: Medium Aerial Swooper

Aerial Spore Diver

Winged biomechanical predators that emerge from the thick fog layer miles off the Wall face. They dive at extreme angles to drop corrosive bile sacks directly onto rooftops.

Armor Class: Light Chitin

Primary Target Priority: Cliff Wind Turbines, elevated sensor towers, exposed solar arrays

Tactical Counter: Dedicated anti-air flak batteries positioned on high crane pylons.

Threat: High Wall Crawler

Carapace Breacher (Armored)

Bulky, heavily armored bio-tanks possessing reinforced frontal plates capable of deflecting standard kinetic flak bullets. They charge structural support pillars to destabilize entire colony sections.

Armor Class: Heavy Carapace

Primary Target Priority: Structural elevator shafts, foundation anchor bolts, Command Core Hub

Tactical Counter: Focused Laser Batteries; armor-piercing kinetic rounds; EMP stuns to halt momentum.

Threat: High Stationary Artillery

Bile Artillery Strider

Mounts itself onto distant, unreachable rocky ledges hundreds of meters away, lobbing high-arcing biological corrosive mortar rounds into the center of your settlement.

Armor Class: Heavy Carapace

Primary Target Priority: Industrial refineries, power plants, medical pods

Tactical Counter: Long-range railgun batteries or sending a combat-fitted Robo-Spider to assassinate it.

Threat: Catastrophic Burrower

Zyrex Colossus (Leviathan)

Massive, ancient boss-tier biomechanical abomination that tunnels through the inner core of the Wall, rupturing out through the cliff face in a devastating seismic tremor.

Armor Class: Hardened Alloy

Primary Target Priority: Entire vertical sectors, deep borehole mines, main command infrastructure

Tactical Counter: Full colony defense mobilization: coordinated laser batteries, EMP shockwaves, and concentrated heavy fire.

Environmental Hazards & Emergency Events

Dynamic Cliff Events

Hazard Alawar Confirmed Event

Sub-Zero Cryo Mist Front

Freezing gale winds surging upward along the cliff, coating machinery in thick rime ice.

Colony Impact: Freezes cliff wind turbines (-80% output), increases heating energy demands by 40%, slows elevator transit.

Mitigation Strategy: Geothermal heating loops, internal backup battery banks, heated cable conduits.

Disaster Alawar Confirmed Event

Deep Wall Seismic Tremor

Tectonic shifts inside the ancient monolith structure triggering rockfalls and structural strain.

Colony Impact: Inflicts 15-35% structural integrity damage to unreinforced overhangs; risks collapsing gravity chutes.

Mitigation Strategy: Heavy foundation anchor bolts, hydraulic structural dampeners, avoidance of excessive cantilevered buildings.

Hazard Alawar Confirmed Event

Pressurized Gas Pocket Rupture

Drilling into the Wall breaches an ancient pocket of combustible subterranean gas.

Colony Impact: Toxic air leakage into adjacent mines; risks explosive fire if exposed to induction smelters.

Mitigation Strategy: Atmosphere scrubbers, automated blast doors between mining and residential sectors.

Warning Alawar Confirmed Event

Worker Strike & Civil Riot

Morale collapse resulting from prolonged food shortages, severe overcrowding, or unburied casualties.

Colony Impact: Halts factory production chains; miners refuse to operate high-risk boreholes.

Mitigation Strategy: Construct recreation hubs, upgrade to Tier 2 housing, ensure stable hydroponics supply.
