Welcome back, jagger. You'll find a few changes since you last battled on the Grid. We've added some surprises to make things more interesting. Even though you have some new programs at your disposal, don't get too cocky, there's always a better jagger out there. Three new program sets! The Delilah, Ezra, and Natasha program sets add more options for building your own program sets. Some programs introduce new command abilities, while others are new versions of previous command abilities. Two new command abilities! Halt will shut down a program and prevent it from attacking or using a command ability. Barrier will prevent a program from taking damage. New logic bombs! These new logic bombs don't reveal cards in the Grid. Instead, they have abilities that will help or hinder all players. Random seeds! Random seeds will change the state of the Grid. Each game will be different, as the random seed chosen for that game will alter the rules. Jagger Arena: Delilah is an expansion that requires the Jagger Arena core set. —description from the publisher
