Player inactivity levels in missions are monitored by the game in both public and solo matchmaking sessions. Being dead or inactive for more than 1 minute disqualifies the player from either the end-of-mission reward or the end-of-rotation reward depending on the mission type.[1] This event is highlighted with the message: “Not eligible due to inactivity”.
Mechanics[]
The penalty is triggered by the player not moving more than ~5 meters for 1 minutes, even if the player is killing enemies via abilities. This includes dying and not reviving for 1 minute. Killing enemies with weapons, however, will prevent inactivity penalty from kicking in by resetting the 1-minute timer.
The player is not considered inactive if they are standing in the extraction zone.
Any affinity sharing and energy generation are halted until player activity resumes.
Wukong's Celestial Twin will cease all activity and remain unmoving until player activity resumes.
The same goes to Excalibur Umbra while in Operator mode and Tenno Specters, in which case they will kneel until player activity resumes.
The Inactivity Penalty will now cause your Warframe to drop any crucial mission items (ex: Data Mass) if you are inactive while in control of Operator.
This is to allow active players to continue on the mission by picking up those items from the inactive player.
Players will now be disqualified from end-of-mission rewards if they've been dead or AFK for over a minute. This will not affect players that are waiting at extraction. This timer only matters relative to when the mission is completed. It isn't a 'catch all' net for 100% of the mission.
Pool 1) Survival, Defense, Interception, etc rewards are revealed during the mission and accumulate without penalty.
Pool 2) Exterminate, Sabotage, Capture, and essentially anything else that isn't endless have end-of-mission reward items (Blueprints from bosses, etc).
Pool 2 items are all that is affected by this change at this time.
