Players must avoid TR3-VR and activate the switches to open the door at the back of the maze that leads to a small room with 4 elevators that will fall down right before they reach the upper level. After awhile the players encounter a giant maze-type of room with 4 switches that must be activated in order to progress, guarded by TR3-VR (Trevor), a sweeper bot that stalks the corridors.
Some rooms have switches that can be activated to make the route easier for those behind. After clearing everything they must run through maze-like ventilation system and rooms with jumping puzzles. Players must clear all the enemies from each room before they can proceed forward. The mission starts at old tower (the place where Amanda Holliday rendezvous with the Guardian in Homecoming), which is overrun by Fallen. The mission is similar to The Whisper in the way that players are given 20 minutes to complete it and that some enemies have Elemental Absorption shield on them. One singe challenge also gives the player 67 SIVA Nanites, resulting in 3-week catalyst completion, if done in all singes. To complete this bounty, the player will need to complete the challenge on all 3 weekly singes (Void, Arc, Solar) which then awards the Scrap CF-717-91. The heroic version also allows the player to complete a Whisper-like secret challenge to obtain Ship Schematic Exotic Bounty. After the player completes the heroic version of Zero Hour for the first time, further completions will award 100 SIVA Nanites which count towards completing the Outbreak Perfected Exotic catalyst. When the player completes the heroic version of Zero Hour for the first time, they will be awarded the Outbreak Perfected Exotic catalyst. 3 Obtaining the Fallen Transponder and activating the nodesĪfter the completion of the quest, a heroic version will be available via an option after selecting the Zero Hour mission on the Earth directory.
