$36 on the Urban Decay website.
I will go over the shadows that are found in the Ammo Shadow Box, descriptions taken from Sephora:
Smog - deep coppery bronze, this is a beautiful buttery brown everyday crease brown colour.
Maui Wowie - sandy sheen, I thought this shadow would be too glittery, but it's actually not horrible when swatches, pretty smooth gold champagne colour, extremely pigmented.
Mildew - shimmering metallic green, I don't have a lot of green shadows and this one is beautiful.
Last Call - iridescent plummy purple, one of the prettiest purples ever, love this shade and my favourite in this palette.
Chopper - shimmering fawn with glitter. Peachy colour with subtle shimmer.
Shattered - bright iridescent aquamarine. Pretty oceany blue with no shimmers, glitter anything.
Sin - light shimmering champagne, this is another beautiful colour, shimmer is delicate and the shadow is smooth and lovely.
Oil Slick - black with rainbow glitter. I have this in the Sustainable palette too and hate it, never wear it.
Polyester Bride - sheer white shimmer, crumbly, thick mess.
Grifter - sparkling pale purple ,too much fallout and crumble on this one.
This palette is really nice, the packaging is cool and the shadows contained are pretty good, aside from the three "losers" that I pointed out above. I am happy that I have this palette in my collection and reach for it from time to time. I only have the two for now, Sustainable and Ammo and I would choose Ammo over the other in a second.
If you are thinking of picking up an Urban Decay palette, please keep in mind that their shadows can be crumbly, glittery and have lots of fallout, but some shadows are also very, very good quality and some of those are in this palette.
