Get to the first tower and destroy the wave generator | Shutdown Halo 4 Guide
Last update: 11 May 2016
Enter Pelican shown on the screen. You'll pass stands with various weapons. You have to pick up DMR with full ammo.
After a cut scene, fly out from the tunnel and head to a tower on left. Before you get to an entrance, fire down all Banshees.
When the landing site is safe, enter the building. After passing few doors, you get into a huge room. Move on right of gondola (screen) and activate it. On the lower level of platform you find weapon stands and grenades.
When you go, a sniper shows up on right. Kill him. In one third of the way, gondola will be stopped. Hide somewhere and kill enemies before you move on.
Approach your goal very cautiously, monitoring where your enemies are. The panel will be well protected. After killing all enemies, activate gondola and return to it. On the way back, you'll be attacked by Knights and Crawlers, who'll defend an access to gondola.
When the gondola starts, two Knights appear at its bow. When you eliminate them, more enemies show up on left. Gondola will be stopped again. Repeat actions needed to launch gondola and cautiously killing enemies.
When you launch gondola, once again Knights show up. When you do them in (one of them drops Autosentry module, which you should pick up) enter the beam of light (screen). When generator is launched, a big group of Watchers appear. Go down and use module. When you kill them all, return to gondola, activate it and move back to Pelican.
