Marvel Pinball at no charge.
Like all of Zen's recent pinball games, Marvel Pinball is less a game itself, and more a shell that DLC tables can be bolted onto via in-app purchases. Those tables are usually priced at $2 each, but the gratis game also includes the Avengers table Zen released in 2012.
If you're intrigued by this offer, don't put off downloading Marvel Pinball. This discount is only available for the next week, after which Marvel Pinball will return to its standard $1 price.
