Amour

To get different armor, just get achievements, different achievements get different armors. I.E collect all skulls and you unlock Hayabusa armor.

Hope this helps.

Certain achievements unlock certain types of armour(some achievements are only available on xbox live). But for the hayabasu armour you have to collect skulls, and some armour is only available to bungie members and other selected people.

Unlock Katana:
When you've completed ALL the Achievements and found ALL the skulls Katana becomes unlocked. There are more armors that I forgot, but this is the majority of them.

I sugest completing the entire game on legendary. And then doing little things in campaign to get more armor-}

You need to get certin achievements to get the armor.

All of the armour in halo is pretty sweet but I think the coolest looking armour is the hayabusa ninja armour. To unlick it you need to get all the skulls either on heroic or legendary. Hope you choose to unlock this armour cause it's worth it.

Just get achievements. Certain achievements get you armour.

You need to keep unlocking achievements to unlock armors.

Certain missions with in the campaign will unlock some but most you unlock from multiplier.
