Data Processing Terminal - Return | Walkthrough Quake 4 Guide

Very short level. Through the major part, you are doomed to the observation of the huge creature, who will be trying at all costs to destroy the cabin. Eventually the enemy will hang up on it (#199) and you'll start to fall very quickly. Don't worry - you won't get hurt.

When you regain control, you'll notice surely that you are located very close to the railway that brought Kane to this tower. Use the elevator located on the center of the hall and travel down. Safe and sound, run straight ahead and enter the carriage (#200).
