Dear Imperial citizen, the apocalypse has begun, please follow the instructions sent by departmento munitorum:
-find shelter
-have faith and pray for the emperor
-stay hidden untill Imperial forces secure the segmentum.
But in all seriousness, the new WH40k expansion was just relesed. Apocalypse is a game mode for huge battles involving hundreds of models, dozens of vehicles and towering titans. You can see the new stuff here
