Stealthy Operations is a recurring Helix Rift Event in Assassin's Creed: Rebellion that originally lasted from December 7-10, 2018. It comprised of six missions in which members of the Spanish Brotherhood who were adept in stealth infiltrated Templar strongholds in Spain, stealing resources and evading members of the Spanish Rite. Successful mission synchronization gave players Data Nodes which unlocked various reward tiers based on the total Nodes collected, with the top tier granting players the character Shao Jun to play in future missions; a sword, set of medium armor, and accessories scaled to one's Brotherhood level; and coins. Players could earn extra Nodes if they used one or more of the following Sync Bonus Heroes:
|Hero||Bonus Data Nodes|
|Máximo Barrosa||25% initially, +25% for each additional rank|
|Luis Chico||50% initially, +25% for each additional rank|
|Flora de la Cruz||75% initially, +25% for each additional rank|

- This Event is one of the few that does not have a changing roster of Synch Bonus Heroes, the others being DPS All-Stars, Swift Assassination, and Freerunner Frenzy.
