I thought i would start a thread where we can all help each other to better our scores. I've been spending a lot of time trying to Perfect my OD's on master and also experimenting a little when to use them. Lets start with Acis I'm going to attach a vid of a 116 mil run stacking Humans to the left of Portal and also a 114 mil run stacking to the right. If this helps anyone brilliant but also if you think you can see places for improvement let me know. I will add more video's of later levels if the thread is of interest to anyone at a later date.
