How to get: Painbow Connection Achievement

[Sayori]

So with the new DLC, there's 1 secret achievement that I found out today how to do it:

Check the image above for the secret achievement details (and proof I've done it).
All you need is 4 rainbow guns, 1 rainbow grenade, 1 rainbow shield and 1 rainbow relic.

No class mod needed.

There are plenty of guides online on how to farm the various items needed.
Happy hunting!
