'''''We're In This Together''''' (also known as '''''[[Halo numbers|Halo 15]]''''') is actually a collection of 3 CDs distributed in Europe and Japan to promote the single "[[We're In This Together (song)|We're In This Together]]" from the album ''[[The Fragile (halo)|The Fragile]]''. Due to its rarity when released, along with the fact that the single was not officially released in the US, this collection is a very coveted item for NIN memorabilia collectors.
The singles were also released in Japan, with Obi strips attached to the artwork. No commercially available vinyl or cassette versions were released.
