Path of Exile 2 is an upcoming game from Grinding Gear Games, set to expand and evolve the world introduced in the original Path of Exile. Announced initially as an expansion in 2019, it has since grown into a full sequel, with a new campaign, updated graphics, reimagined character classes, and refined mechanics. Here are some key aspects:

1. Two Campaigns in One World: Path of Exile 2 introduces a new seven-act campaign that runs parallel to the original. Players can choose to play either campaign while sharing the same endgame content, including the iconic Path of Exile maps and leagues.
2. Skill Gem System Overhaul: The skill system is receiving an overhaul, with each skill gem now able to contain support gems, significantly streamlining the linking process. This allows more flexibility in skill customization, making build experimentation easier.
3. New Ascendancy Classes: New ascendancy classes are being introduced, with a total of 19 different class choices across both campaigns. Each class features unique mechanics, promoting diverse and fresh character builds.
4. Improved Graphics and Animations: Path of Exile 2 features upgraded graphics and smoother animations, leveraging modern rendering techniques for more immersive gameplay.
5. Release Plans: Originally aimed for a release around 2022, Path of Exile 2 was delayed due to various challenges, including the pandemic. Grinding Gear Games has suggested a tentative release date in 2024, though it could change depending on development progress.
