Marathon: How to Complete Introducing: NuCaloric – Fast Route

The Introducing: NuCaloric contract in Marathon is completed on Perimeter, in the Columns area, by doing two actions in a single deployment: loot the NuCal employee ID/access card from the infested building, then use the nearby terminal to download the employee data. The contract registers on the terminal interaction. Extraction is not required for completion, but dying or leaving before the terminal step breaks the run and forces a full repeat.

What the contract actually requires

This is not a broad scavenger hunt. It is a fixed-objective route with a strict sequence. Current route consensus is consistent on the essential requirements even though the item name varies slightly between guides.

• Deploy to Perimeter.
• Go to the southern Columns section, between Overflow and South Relay.
• Enter the Tick-infested NuCal building.
• Activate power inside if required by the interior state.
• Loot the NuCal employee ID/access card.
• Use the terminal in the same building to download the data.
• Do both actions in the same run.

The single-run condition is the part the game communicates poorly. If you loot the card, extract, and then come back for the terminal later, the contract does not count. If you die after the terminal download, the objective should still be complete, because the completion trigger is tied to the terminal interaction rather than extraction.

Fastest route to the building on Perimeter

The target structure is in the southern portion of Columns, between Overflow and South Relay. Visual descriptions differ slightly across guides, but they describe the same place: a one-story structure marked with either a large white 2 or 02, with obvious orange Tick contamination around it. Do not over-focus on the exact number styling. The shared identifier is the contaminated building in that sector.

The fastest approach is from the east side. The ground-level entry is commonly described as unusable at first, so the efficient route is to take the exterior ladder, get onto the roof, and force the hatch. That saves time and avoids circling the building while exposed.

• Approach from the east side if possible.
• Find the exterior ladder.
• Climb to the roof.
• Open or smash the roof hatch.
• Drop directly into the interior.

This route is fast, not safe. Because the contract objective is concentrated into a single building, other players can converge on the same location even in solo matchmaking. Treat the roof and ladder as contested angles. If you hear movement below or metal footsteps behind you, assume another squad or solo player is timing the same entry.

Interior sequence: clear, power, loot, terminal

Step 1: Clear the immediate Tick pressure

The building is consistently described as Tick-infested, with multiple nests or pods capable of generating continuous pressure if left intact. The efficient play is not to sprint straight for the shelf and hope the room stays quiet. Remove the nests first, or at least the nearest ones, so the building stops escalating while you search.

This matters because the contract is lost more often to clutter than to raw difficulty. Ticks force reloads, chip health, and obscure audio. If you are trying to distinguish nest sounds from player footsteps, leaving the room alive with ambient enemies is a poor trade.

Step 2: Turn on the power if the doors are not fully active

Several route breakdowns note that interior access can depend on activating power after entry. If you drop through the roof and the building feels partially locked or segmented, look for the power interaction first. Once the power is on, interior doors and normal pathing become easier to read.

Do not waste time trying to brute-force every door before checking this. The building is small enough that a delayed power activation costs less time than a panicked full sweep under Tick pressure.

Step 3: Loot the NuCal employee ID/access card

The pickup location is functionally consistent even though directional descriptions differ. After entering, the card is reported in the room to the right of the doorway you use from the interior route, usually resting on a shelf or counter. Some guides describe it as “on the shelf,” others as “on the left side of a counter or shelf” depending on the player’s facing. Those are not contradictory; they are orientation differences inside the same room.

If you are standing in the correct room and do not see it immediately, slow down and scan the waist-high surfaces instead of checking the floor. The item naming may appear as employee ID, access card, or NuCal employee ID. The label variation does not change the objective. The correct interactable is the card tied to the nearby terminal step.

Step 4: Use the terminal in the same room

After picking up the card, interact with the terminal nearby and download the employee data. This is the actual completion trigger. If the download completes, the contract step is done. At that point, extraction is optional from a contract perspective. It still matters for keeping gear and any extra loot, but it is not required to advance the objective.

That distinction changes how aggressively you should play the exit. If you arrived specifically for the marathon nucaloric contract and the terminal has already been used, the rational choice is to leave immediately by the fastest available route instead of turning the run into a full loot clear.

Common failure points that waste runs

• Splitting the objective across multiple deployments. Looting the card in one run and trying to use the terminal in another does not complete the contract.
• Searching for a normal front-door entry. The roof route is consistently the fastest and most reliable.
• Ignoring Tick nests. Spawn pressure turns a short interaction into an attrition fight.
• Leaving after the pickup but before the download. The terminal is not optional.
• Over-searching the building. The contract path is narrow; unnecessary room checks increase exposure to players rotating in.

If the contract did not register, the first thing to verify is sequence rather than location. In most failed attempts, the player either left before using the terminal or died between the two objective steps. The building number, exact shelf phrasing, and item label are secondary details. The run logic is what matters.

Efficiency and survival notes for contested runs

Because this is one of the early Marathon faction contracts, the site can be unusually busy. The route is short enough that multiple players may hit it within the same early window. Efficiency is so a survival tool, not just a speed tool.

• Approach with enough burst damage to kill Tick nests quickly.
• Pause briefly before climbing the east-side ladder and listen for roof movement.
• Once inside, clear only what blocks the objective path.
• Do not hold the building after the terminal download unless you need the loot badly.
• If another player arrives mid-clear, prioritize line of sight and completion over chasing.

The practical logic is simple: the contract pays for completion, not for winning an extended building fight. Every extra second spent inside after the terminal interaction is voluntary risk.

Rewards, faction reputation, and progression value

The immediate reward for Introducing: NuCaloric is progression through the NuCaloric contract line and the associated faction reputation gain that comes with contract completion. That is the reason this mission matters for players working through Marathon faction contracts efficiently. The provided evidence does not establish a consistent numeric reputation value, so it is safer to treat the meaningful reward as unlock progression rather than a fixed rep figure.

In practice, this contract functions as a gate. Completing it cleanly opens the path to further NuCaloric work, which is more important than squeezing extra value from the same deployment. If your objective is faction advancement, the optimal run is narrowly scoped: reach Columns, roof-entry the building, clear enough Ticks to move, activate power if needed, take the card, use the terminal, then disengage.

Final route summary

For the marathon nucaloric contract, go to Perimeter and head to the southern Columns area between Overflow and South Relay. Find the contaminated NuCal building marked 2 or 02, take the east-side ladder to the roof, drop through the hatch, clear nearby Tick nests, turn on power if the interior requires it, loot the employee ID/access card from the right-hand room, and use the terminal in that same room. The terminal interaction completes Introducing: NuCaloric. Extraction is optional after that point.
