Land the Falcon on Kefka’s Tower and assign three parties.
Walkthrough
Land the Falcon on Kefka’s Tower and form three parties. Put recovery, revival and varied attacks in every group; the teams take separate routes through machinery, conveyor belts and ruined rooms. One group will often need to stop while another opens a route.
Advance the second and third groups along their routes and use switches to open the way for the others. After 
Inferno, repair the broken walkway for the first group. At the upper junction, use the heavy weights and switches to let all three groups reach their paths. Guardian and the three statues protect the ascent. If 
Strago needs ForceField Lore in the original game, arrange for him to fight Doom.
After defeating Doom, 
Goddess and 
Poltrgeist, move all three groups onto their final switches. Save at available points, set the order for the final battle and heal before approaching Kefka. After victory the escape and ending are scripted; retain a pre-tower save for unfinished exploration.
Checkpoint
To coordinate the final tower, advance the second group to its switch and the third group through Inferno. The third group can repair the broken route for the first. At the upper junction, use both side switches to open the center, then move the weights so the other parties can climb. Guardian precedes the statue routes; all three statues must fall before the final switches open the ascent.
