Campaign- Worst: Regret Favourite: Metropolis Multiplayer- Worst: Sanctuary Favourite: Ascension it was hard for me to decide between The Great Journey and Metropolis, both amazing levels. couldn't decide which was worse out of these 2: Regret and Delta Halo but the Regret boss battle on legendary was a pain in the ass so Regret. Sanctuary was my least favourite map because it had the temple ruins them of delta halo/regret, Ascension was my favourite because i had so many fun Juggernaut matches in it.
