Call of Duty: Black Ops 2 Zombies introduced TranZit, a sprawling fog-covered map that fundamentally changed how survival gameplay worked by introducing buildable items. Players must navigate across distinct zones to collect specific components and assemble powerful gear on workbench locations scattered throughout the map. Understanding where to locate these essential items and how to assemble them is crucial for surviving high rounds against the relentless undead horde.

Bus Stop and the Essential Turbine

The journey begins at the Bus Depot, where players can assemble the Turbine using three specific components found around the starting room. You need a mannequin torso, a toy bus control pad, and a fan blade, which are typically scattered across the benches and floor areas. Constructing the Turbine at the nearby workbench provides portable power, allowing you to open perk doors and activate map utilities early without spending precious points.

Diner Upgrades and Defensive Buildables

At the Diner stop, players can assemble the Zombie Shield to protect their rear side from incoming attacks while traversing fog-filled routes. The shield requires a car door and a heavy-duty shopping cart, both located inside or around the diner garage structure. Mounting this item on your back absorbs incoming damage from behind, making it an indispensable asset for solo runners and cooperative teams alike.

Farm Utilities and NavMesh Power setup

Moving forward to the Farm, players find components to craft the Turret, an automated defense mechanism that shoots nearby zombies when powered by a Turbine. This buildable requires a lawnmower, an assault rifle receiver, and a medical bag found around the barn and farmhouse buildings. While effective at guarding choke points, it relies heavily on strategic placement and continuous power management to remain functional during chaotic encounters.

Power Station and the Thrustodyne Aeronautics Jet Gun

The Power Station contains the components necessary to restore electricity to the map, including a panel lever, a wire spool, and a severed zombie arm. Furthermore, players can assemble the legendary Jet Gun wonder weapon by gathering four distinct parts located across different fog zones and bus stops. Collecting the jet engine, wires, handbrake, and pressure gauge requires careful navigation, but the weapon delivers immense destruction against massive zombie trains when used correctly.
