In another section, a tiled wall is destroyed realistically, with tiles breaking and popping off the wall when they're hit sufficiently hard, while further demonstrations of the engine's prowess include human shaped "rag doll" models in glass boxes, which react realistically to the environment around them being damaged, and most impressively of all, a completely interactive piece of cloth suspended between poles - which billows and stretches when it's shot, and can even be filled with balls like a hammock.
