There are a range of huge dioramas in Warhammer World in Nottingham. One of them involved Imperial Titans attacking a T’au base.
The Reaver Titan was marching forward despite being repeatedly attacked by T’au forces.
T’au battlesuits flew over the attacking forces attempting to stop them.
It was an impressive display and included a huge T’au Manta as well. The scenery is excellent representing a T’au base or colony.
