From SWTORista.com:

“The Rakghoul Resurgence, better known as the “Rakghoul Event”, is a limited-time event in Star Wars: The Old Republic. This event happens sporadically, and rotates between the planets of Alderaan, Corellia and Tatooine. The event focuses on the outbreak of the Rakghoul virus, and during the event you’ll travel to the rakghoul tunnels that have been dug deep underground.”

This competition is based on a 1-week event, “Rakghoul Resurgence,” that runs from March 21 to March 28, 2023.

Objective: Be the quickest to submit screenshots showing completion of the 4 [Daily] missions and 1 [Heroic 4] mission available from the mission terminal inside the Rakghoul tunnels, the 1 hidden [Daily] mission “Spreading Infection,” and the one-time mission “Jeelvic's Datapad” (7 screenshots total). Ideally, you should take screenshots of the “mission complete” pop-up that provides your rewards, but if you accidentally click accept on the window, screenshots showing the mission completion from your chat window will also be accepted.

It is only required to complete missions from one faction, either Imperial or Republic.

[DAILY] Collecting Raklings
[DAILY] Dissecting the Plague
[DAILY] All That Remains
[DAILY] The Tunnel Network
[DAILY] Spreading Infection
