So, after many attempts during my first playthrough of LWS4, I decided to complete LWS4 before replaying for the achievement. I recently tried doing just that but I realised, after each failure, I have to again fight off the waves of awakens and wait for Canach to finish blowing the gates and going all the way to the lasers before I can re-attempt the achievement. That's many un-skippable minutes before each and every attempt at the achievement! How does this make sense?! Is there another way to do this without having to go through all the dialogues and fighting those waves of awakens?
