Control Resonant: All Taxi Locations and Puzzle Solutions for 'The Last Taxi' Quest

Completing "The Last Taxi" side quest in Control Resonant requires players to locate several driverless taxis scattered throughout the game's world. Upon entering these taxis, players are transported to a threshold realm where they must solve a puzzle related to paranatural abnormalities. The quest narrative involves helping a trapped woman named Mila find her way out. While the puzzles are distinct for each zone, the taxis themselves can be found and completed in any order.

Players can identify taxi locations by listening for their distinct horns, which will sound persistently when a taxi is nearby. After entering a taxi, it is crucial to interact with the payphone within the associated alleyway to advance the quest and learn more about Mila. The puzzles generally involve identifying a specific taxi based on subtle visual cues or patterns, such as lights or their behavior relative to their surroundings.

Central Taxi Location and Puzzle Solution

The taxi in Central is situated in the northwesternmost alleyway. Players can reach it by heading west across the rooftops from the Patterned Factory. After entering the taxi and interacting with the payphone, players must solve the following puzzle:

1. Enter the car with its rear lights illuminated.
2. Enter the vehicle displaying its taxi light.
3. Among eight cars, identify the one with both headlights and rear lights on, as others will have one set on and the other off.

West Incursion Zone Taxi Location and Puzzle Solution

In the West Incursion Zone, the taxi is located near the Empire Avenue Station entrance. Backtracking from the "Empire Avenue" fast travel door and taking the first left after the station will lead players to the taxi. The puzzle here involves observing streetlights:

1. Enter the taxi positioned beneath a blinking streetlight.
2. Enter the taxi that does not have a streetlight blinking above it.
3. Identify and enter the taxi whose streetlight blinks at a different interval than the others.

Evacuation Zone Taxi Location and Puzzle Solution

The taxi in the Evacuation Zone can be found at the end of an alleyway northeast of the "Unauthorized mines?" map marker. Proceeding east in this alley will reveal the taxi. The puzzle requires attention to the taxi lights:

1. Enter the taxi whose light blinks at a different interval.
2. Enter the taxi whose lights blink twice.
3. Enter the taxi that has no lights on when the surrounding streetlights are active.

Downtown Taxi Location and Puzzle Solution

To access the taxi in Downtown, players will need the "Reach" ability, unlocked from the Subway Fault in the Evacuation Zone. From Lookout Point on the east side of Downtown, use Reach to access the easternmost region. The taxi is located north of this area, among other vehicles. The puzzle focuses on identifying the correct taxi light:

1. Find the taxi cab with its taxi light illuminated.
2. Enter the taxi whose light remains on when the player is near it.
3. Identify the taxi whose light activates when near a different vehicle.

The Park Taxi Location and Puzzle Solution

The taxi in The Park is in the same parking garage as the vendor, one floor below the ice cream truck. From the vendor, head south into a mold-filled hole, then follow the path to the second-highest floor of the parking garage. The puzzle here involves reattaching car parts:

1. Destroy any mold growth and reattach the correct car parts to the taxi.
2. Attach the tires and the yellow car hood.
3. Complete the attachment process, but do not add the police siren or white car trunk.

Underpass Taxi Location and Puzzle Solution

The Underpass taxi requires players to cross a chasm, typically encountered during the "Recursions and Iterations" quest after riding the cable car. In the subsequent mold-filled area, proceed to the northeast corner to find the taxi on an elevated platform. The puzzle involves observing streetlights and taxi lights:

1. When streetlights turn off, find the taxi whose lights remain on.
2. When streetlights turn off, find the taxi whose lights also turn off.
3. Locate the taxi that has no lights on while the streetlights are active.

Unknown Taxi Location and Puzzle Solution

In the Unknown zone, the taxi is on the southernmost island, near the Evac Building. Facing the Evac Building, move to its right to find the taxi. This puzzle requires careful observation of shadows:

1. Find the taxi cab whose shadow is also a taxi cab. This solution applies to all three steps of this particular puzzle.

Upon completing all taxi puzzles, "The Last Taxi" quest concludes without offering any specific in-game rewards. However, successfully finishing this quest contributes to the requirements for the "Threshold Researcher" achievement, alongside the "Crossing the Threshold" and "Unsupervised Science" side quests.
