I have a K90 keyboard and just created some macros. One just cycles through W, up, A, left, S, down, D, right and that hasn't failed a QTE yet.
Another does the A D hammering for that bar thing.
The third does Carla's breathing for me.
Only the last one took a few goes to get right.
I competed the game many years ago so have already done it all without this cheating. Now I can actually just watch what is going on without having my eyes glueg to the QTE icons and missing it.
