I'm shocked by how low-rated this is, I had an absolute blast playing through it solo. It felt like such an upgrade compared to Trilogy, with weapon and perk progression making me genuinely want to grind a bit. The horde mode being changed to have progression similar to COD Zombies improved it from a mid gamemode to something I'd actually want to go back to. While the DLC being shoved in my face is annoying, the fact that we get 12 full chapters for free is pretty insane already, so I didn't mind that much.
