Kate is a green gem character with secondary yellow and over-power green as her power. The level is great fun to play featuring wave after wave of Cybermen starting with little teeny ones!
There are also new costumes available – the Brigadier as a Cyberman and Danny Pink as the Cyberman with no face mask. If you look in the Expert Levels you can get the War Doctor as long as you have a party that includes 10th+, River+, Strax+ and Clara+. The level is called Confusion and is the hardest level yet (we are told).
