Hello Wipeout Fans!

I have come back to play Wipeout 2048 since some months ago, and I'm trying to master the expansions HD & Fury.

But the fact is that I'm unable to understand how the Detonator Mode works in the Fury DLC. The manual doesn't explain so much, and I don't know how to use the EMP, whatever it is.

I have realized that when passing over the pannels you begin to activate this EMP, and after some of them the girl-narrator tells you that this is activated. So then I would like to use it, but I don't know how to do it. I did it once, and at that moment I thought that it could be by pressing the "x", but didn't work again.

If anybody could explain it... I would thank it a lot, because without it I am not so sure about earning the gold medals in those events.

PS. The Fury expansion is beautiful, though I don't like too much those combat events. On the other hand the HD expansion is great by any point of view. I haven't PS3 so I'm so happy to play it in the Ps Vita.
