Hellioskrill Possible With Missions?

So, I know that the Hellioskrill armour can be unlocked with Gold Packs, and that the legendary achievement doesn’t unlock hellioskrill but when the game says you’ve completed all missions on legendary. So, my question is can you get the Hellioskrill armour and helmet with some mission done solo legendary and some on Co-op, or does it have ro be full solo or full Co-op?

Please someone who has done this answer. Thank you!

You need to complete it full solo or full co-op, you can’t do a mix of the 2

Okay, and I’m assuming I can’t have skulls turned on? Because for some reason MCC doesn’t record a mission being completed if I have skulls turned on

Some skulls are fine to have on. But any skull with a 0.0x multiplier will negate any achievements, as well as unlocking Helioskrill (so basically no Bandana, no Scarab, or any other “easy mode” skulls).

Alright, I’ll look up some speedrun guides and try to avoid as much enemies as possible in the campaigns. Thank you two for the help
