Gotta love TF2's gimmick levels. I won't spoil all of them, because I think Respawn deserves all the respect they can get for the Cause and Effect chapter. But I will happily share footage of the mesmerizing house factory level in the mission Into the Abyss for anyone unfamiliar: https://youtu.be/oOaHzR7jnJ0?t=420

We may never get a shooter campaign level that tops fighting robots on a prefab assembly line...
