On the official website, Bethesda claims, “the party doesn’t stop when Rage 2 launches on May 14. With events, community challenges, new vehicles, additional enemies, new Cheats, and two huge expansions, Rage 2’s calendar is pretty packed for the rest of 2019.”

Beginning launch week, Bethesda will add free new content including community challenges, world events, weapon skins, and cheat codes from the game’s release in May until the Fall. However, in August and towards the end of the year, two major expansions will be released which will add a new story, enemy faction, weapons, abilities, vehicles, and new areas to explore. There is no current pricing on these expansions as of yet.
