Corporate Secrets Tarkov quest: Mechanic's 4 objectives on Lighthouse
Corporate Secrets is a 
Mechanic quest on Lighthouse in Escape from Tarkov (EFT). It opens at Mechanic loyalty level 3, once you finish 1 other Mechanic task at that level, and needs no key. You bring Mechanic 2 documents from the water treatment plant.
| # | Objective | Where |
|---|---|---|
| 1 | Locate and obtain the data on the water pump operation | Water treatment plant, Lighthouse |
| 2 | Hand over the  Water pump operation data | Mechanic |
| 3 | Locate and obtain the data on the pumping station operation | Water treatment plant, Lighthouse |
| 4 | Hand over the  Pumping station operation report | Mechanic |
The 2 documents are the Water pump operation data and the Pumping station operation report. Each is a quest item with its own hand-over objective.
Corporate Secrets Lighthouse locations: 2 documents at the water treatment plant
Both documents spawn at the water treatment plant in the north of Lighthouse. Each document sits in an upstairs office of a different building.
| Building | Floor and room | Spot | Spawns |
|---|---|---|---|
| Building 1 | 2nd floor office | On a shelf | 1 |
| Building 2 | 2nd floor office | On a desk | 1 |
The 2 buildings hold the Water pump operation data and the Pumping station operation report. Each document has 1 spawn point, so its spot stays the same every raid.
Mechanic warns that someone guards the plant. Come with a full kit and enough ammo for a long fight.

After Corporate Secrets: Kappa status and more Mechanic tasks
Corporate Secrets has no part 2, and no quest follows it. The 
Kappa container does not need it either, so run it for the 28,000 XP and the 275,000 roubles. The Kappa guide lists the tasks Kappa does need.
Therapist and Ragman each have a loyalty level 3 task with the same 28,000 XP and 275,000 roubles. Disease History sends you to Reserve for 2 medical records, and Audiophile sends you to Streets of Tarkov for a guitar pick.
Every Mechanic task LFCarry runs is on the Mechanic quests page. More ways to earn roubles are on the Tarkov roubles guide.
More tasks are on the Tarkov quests guide, and every LFCarry service for the game is on the Escape from Tarkov hub.
