Good runner Trophy in Alteric
Complete Chapter 6 without deads
How to unlock Good runner
The requirement for this trophy is wrong. There are only 3 chapters in the game. What they are referring to is Level 6.
You need to beat the level without dying. It is a rather easy level, so it should not pose much trouble. Take your time and you should be fine. If you die, exit to the main menu and reselect the level from level select.
See 1.36 in the IBaddriverI’s video for a walkthrough.
