You can play with up to three people in Godfall Challenger Edition. You can show off your skills, improve your build, and beat up your enemies. It's free at Epic Game Store.

Godfall Challenger Edition is NOT a full game. It contains the 3 endgame modes but lacks story content from the base game or the Fire & Darkness expansions. The 3 modes included in this free edition are:

• Lightbringer, a battle against an all-consuming darkness that threatens to snuff out all light from the realms of Aperion. Players willing to persevere through selected banes will receive increasingly greater rewards – and face ever more challenging hordes until the blighted Heart of Darkness is banished in an epic final battle.
• Dreamstones, engage in randomized encounters by reliving the memories of Orin and gain unique rewards each time you play. The curses bestowed on the aptly named Cursed Loot tier can be lifted by completing challenges in Dreamstones.
• Ascended Tower of Trials, put your skills to the test in an ever more challenging climb to the top of the tower gaining boons and facing fierce bosses along the way in the pursuit of juicy loot drops.

Just head over to Epic Games Store or navigate to the game in the Epic launcher before December 16th 2021, add the game to your cart and checkout. Simple as that. After that, the game is yours to keep, and play, forever.
