that doesnt answer the question.

- The cloak field is a piece of equipment.
- When selected the cortex is raised and you press fire to activate it.
- Once activated, it goes away and your weapon is raised. You can switch to other weapons/equipment while cloaked.
- You cloak. The amount of "shimmer" is increased as you move so standing still you will be nigh invisible, but when moving you will be noticeable to an extent. When cloaked, you obviously have no chevron or health bars, but the enemy reticule will flash red if you run past it.
- Cloak can be deactivated by selecting it and pressing fire.
- Once deactivated or it runs out it will start to recharge.
- Firing a weapon while cloaked will rapidly deplete the cloak field (a single shot from a sniper rifle, for instance, will decloak you)
- You can only fit one cloak field at a time.

I think you're seriously misreading it. When it says selecting cloak from the item wheel and firing it, it means pressing R1 with the cloak (not the weapon) to deactivate. Not firing the weapon.

Select cloak from Item wheel, and press R1 (fire) to activate.
Select cloak from Item wheel, and press R1 (fire) again to deactivate.
Not about firing a weapon.

EDIT: This is in response to the part you underlined in Remnant's quote.

Looks to me like that last bit of yours is incorrect, based on what CCP wrote.
