Does the quest for beating Ore Chasm count towards the "Did it all" achievement?

Title says it all and I think there is no further text required.

Yes. Every side mission counts, hence the description of the achievement.

These are the missions you are after:

• Hyperion Slaughter: Round 1
• Hyperion Slaughter: Round 2
• Hyperion Slaughter: Round 3
• Hyperion Slaughter: Round 4
• Hyperion Slaughter: Round 5
