This issue is so dumb I feel almost bad about asking it here, but in the Mars mission, they tell you how to turn a corner in cover, and say, I think, use L3. But I couldn't get this to work. How do you really do it?

push L3, simple!

as in click it in!

It's not very intuitive, as clicking downward doesn't make me think of hugging a corner; but I guess it is practical to be able to do so while in cover. I had an a-ha moment when I figured it out, but then I also felt a little dumb because I didn't notice it said L3. I just saw the analog stick icon and tried to do it without clicking L3.

That's what I tried to do, or maybe I tried to do something more complicated than just clicking it. Oh well, thanks.
