There's no level called the cleansing, but if you just landed on The Ark you're about half way through.

Or if you mean the new Halo that's been constructed, you're on the last level.

Im at the point where I did a warp jump I guess to the Halo Ring and I landed on it and have been doing missions on there for about an hour or so
