This package eliminates crashes, unlocks two full waves of story content, adds three new characters, and stabilizes the framerate in co-op mode. Without it, you are essentially playing a beta version of the game.
If you are diving into the world of NSPs and patches, always verify your file sizes, check for the 1.3.1 update, and ensure both "Pulse of the Ancients" and "Guardian of Remembrance" are installed. Once everything is in place, you can finally enjoy the Calamity as it was meant to be played—complete, stable, and ready for battle.
