Okay i managed to rip pretty much every files from Metro, and made a small showcase about the gas mask effect.
1. Download the latest alpha Power Auras:

2. Import this Set into a new Page (Else it will overwrite the current page):
https://gist.github.com/Resike/5684577
And it's pretty much done. It's been made for 1680 x 1050 resolution, so you might need to change on the "Size" and the "Deforamtion" sliders a bit on every aura.
Also you can change color, blendmode, strata, animation, pretty much everything.
If a Photoshop master could change the base yellowish color of the glass to white i would appreciate it much.
