Came with the troll 6 or so months ago when I ordered one. Looks like it still does. As per GW website:
Quote:
The catapult itself is a huge contraption sculpted to look as if it was made from strong wood and Mordor-forged iron. With an immense, metal-bound boulder at one end, it is loaded by a huge, grizzly Troll who wears a mask and little else, and who carries a heavy rock. In addition to this, the kit comes three Orc Warriors to attend to the catapult, each wearing sinister-looking heavy armour.
