After playing through Infernum for the first time, I'd say that this mod can be a pretty fun time for an experienced Calamity player.

The main feature of Infernum is how it completely overhauls all the bosses in the game. Some personal favorites include The Perforators, Skeletron, The Twins, Aquatic Scourge, Golem, Ceaseless Void, DoG, Exo Mechs, and Supreme Calamitas.

Some of the overhauls I'm not really a fan of, though. Profaned Guardians are ridiculously hard for the first post-ML boss, Providence takes an incredibly long time due to her invulnerability phases, and Empress of Light has some pretty unfair attacks (in my humble opinion).

Notably, another big change is how the Great Sand Shark is now a unique boss in its own sub-world. The sub-world itself is very well-done, but the fight itself is pretty mediocre (along with the boss drops and weapons being useless for Rogue). The Adult Eidolon Wyrm is additionally fought after Yharon, and while it's not the most difficult boss in the world it's a fun diversion from going straight to the Exo Mechs.

Alongside the boss overhauls, Infernum also adds a small bit of extra content. There's now a sub-biome in the Underworld where you fight both the Profaned Guardians and Providence, and is also where you get the Wayfinder. It's a neat quality of life item that saves you plenty of time on boss "run-backs," but I just wish its location was more obvious.

Lastly, Infernum does a complete overhaul of the Abyss. I personally never noticed the supposed "food chain" that it implements, but I think it's a good addition/change regardless.

As I stated before, if you're an experienced Calamity playthrough I'd recommend giving Infernum a shot! Even just fighting King Slime will give you an idea of what you'll be in for.
