When you've reached the Rickenbacker, you're firmly in the endgame, though you won't be locked into it just yet. At this point it's recommended you hold off spending your Cyber Modules until you get to the Rickenbacker Bridge unless you really need to, as you'll have a convenient place to spend them all and a ton available to put the finishing touches on your character.

Objective Rewards

• Crossing pipe bridge towards elevator to Rickenbacker Bridge: 15 Cyber Modules

Additional Cyber Modules

• Inside Inverted Chapel, near corpse: 4 Cyber Modules
• Inside green shaft with lots of pipes, hidden at the bottom: 6 Cyber Modules
