Narrative:
It was a normal takeoff. After the gear handle was selected to the up position; we heard an unusual noise; followed by an EICAS message 'hydraulic qty low C.' after switching to departure control we got vectors. The aircraft PF (pilot flying) duties were transferred to the first officer (first officer). We started running the appropriate checklist. Eventually we got an additional EICAS message 'hydraulic press system C.' that checklist was run; in addition to the non-routine landing checklist and the overweight landing checklist. A call was made to the flight attendants to explain the situation; and a PA was made to the passengers to explain the situation. A message was sent to dispatch via ACARS and a tug was requested. Coordination was accomplished with approach and tower. After accomplishing a landing assessment for our conditions knowing we had enough runway; even though we were overweight; we did not dump fuel. PF duties were transferred back to the captain and a landing was made back at [departure airport]. After stopping on the runway; tower requested we shut down all engines. The airport safety personnel accessed our plane. We were tugged to a hard stand.I understand there was a failure in one of the hydraulic lines.

Title: B777 flight crew reported returning to the departure airport after a HYD QTY LOW C EICAS message was received upon gear retraction.
Narrative: It was a normal takeoff. After the gear handle was selected to the up position; we heard an unusual noise; followed by an EICAS MSG 'HYD QTY LOW C.' After switching to departure control we got vectors. The aircraft PF (Pilot Flying) duties were transferred to the FO (First Officer). We started running the appropriate checklist. Eventually we got an additional EICAS MSG 'HYD PRESS SYS C.' That checklist was run; in addition to the non-routine Landing checklist and the Overweight Landing checklist. A call was made to the Flight Attendants to explain the situation; and a PA was made to the passengers to explain the situation. A message was sent to Dispatch via ACARS and a tug was requested. Coordination was accomplished with Approach and Tower. After accomplishing a landing assessment for our conditions knowing we had enough runway; even though we were overweight; we did not dump fuel. PF duties were transferred back to the Captain and a landing was made back at [departure airport]. After stopping on the runway; Tower requested we shut down all engines. The airport safety personnel accessed our plane. We were tugged to a hard stand.I understand there was a failure in one of the hydraulic lines.
