How to unlock the GGO God achievement in SWORD ART ONLINE: FATAL BULLET - Definitive Guide
Despite what the trophy description says, you are not required to play through the entire game on Extreme difficulty (which is unlocked upon beating the game for the first time) but rather, you can easily exploit this by playing through the entire game on Easy or Medium, then before you take on the final boss the second time (regardless of whichever ending you are going for next), exit to the title screen, then go to the game's options and change the difficulty to Extreme. Afterwards, go back to the game, select whoever you want to save and fight against the final boss. Credit to Blitz5 for this tip.
The final boss is level 150 on Extreme but I fought it at level 100 with rank 6 weapons and was able to defeat it without much trouble. You will want to be more powerful if you are going for the true ending on this difficulty.
Extreme difficulty is unlocked after beating the game once on Easy or Normal. However, you don't have to run through the entire story a second time. Use the "Rewind Time" feature after the final battle instead of starting a NG+ run, and simply return to the main menu to change the difficulty to Extreme, reload your save, and beat the final missions again.
At the moment there is no need to play through the entire game. Simply killing the last boss at extreme is enough. The difficulty can be changed at any time in the settings.
