Era
Future
There are two separate sides to the Factory. You need to obtain a password in the right side before you can finish your mission on the left side.
The right side consists of a number of puzzles built around a robot assembly line. Your first objective is to run up the assembly line, starting from the bottom part of the room.
Eventually you'll end up on the top level. The right room will give you two codes to use on the crane (XA and BB). The left room leads to the crane, where entering those codes will cause the crane to clear barrels from the Factory floor. Follow the new path to learn that the password for the Factory is XABY.
The left elevator can be taken down all the way to the bottom immediately, which isn't necessarily obvious. However, you won't be able to access the lower floors before you reach them via other methods. You'll need Robo to access computer screens on each floor to open the way forward. Enter the XABY code at the bottom to lead to the main generator.
Once you turn on the generator, the Factory's security systems go haywire. The elevators will not work, so you'll have to follow the ladders to hatches on each floor. Soon enough you'll run into six blue versions of Robo. You won't have Robo for the Boss fight against them. Crono's Cyclone Tech is highly effective and can be used against a whole row of robots at a time.
