How to unlock the Sine Mora achievement in Sine Mora EX - Definitive Guide
I deleted my safe file and redid the prologue and even then the achievement didn't unlock until a good five minutes of waiting.
You have to choose the advanced pilot route when prompted to accomplish this trophy. I’m not sure if this trophy counts the part before this choice, however just make sure you kill the few ships that come your way and, when you have to face the 2 big ships, use at least 1 subweapon to destroy both in time. After choosing the Advanced pilot route, you will find yourself in a hard-to-navigate trench with narrow vertical and horizontal corridors full of turrets shooting at you. For this trophy, you need to destroy all turrets while dodging their bullets and avoid any contact damage from touching the walls. Note that you can die and continue with no penalties (you will be placed back at the beginning of the trench). In fact, you should suicide on purpose if you get hit to save yourself some time. The screen scrolls forward pretty quickly and you need to balance your Speed Up capsule usage throughout the trench to avoid hitting walls. The turrets are usually in plain sight except for some found in crevices. The trophy will pop after clearing the prologue if you have destroyed everything and have not been damaged.
