This is the Warbringer Nemesis Titan on display at Warhammer World.
The Warbringer Nemesis Titan serves the Collegia Titanica in the role of heavy fire support. It mounts a single Warlord-scale weapon on its upper carapace and Reaver-scale weapons on its arms – sacrificing the speed, armour and manoeuvrability of a conventional Battle Titan in favour of firepower far in excess of its size. Though rare and specialised, the Warbringer Nemesis is a sight to inspire dread in all but the most battle-hardened enemy princeps.
