All I remember is the music video but I need help finding the song. plz help?

So probably about 3-4 years ago now, I saw this music video and I remember I loved the song but I can't remember the name or any of the lyrics. It was a Techno song. the music video was a good looking girl, the background was purple-ish, there was something with an army (of either girls or robots) there was lifting platforms I think and during part of it a girl in the video starting firing lazers and the army or the army fired lazers at her and either the girl in that army were wearing black skintight jumpsuits or the main singer girl in the video. I know I'm not giving very good info, but its all I got.
