What makes The Avengers such a special table is the fact that you get to "play as" each of the six Avengers: Captain America, Iron Man, Black Widow, Thor, Hawkeye, and the Incredible Hulk. Each of these "Avengers" has his/her own bonuses, and your familiarity with the table may eventually dictate which Avengers you want to play as. The "table" hovers high above the metropolitan area at night, and assorted heroes and villains populate the table.
In Fear Itself, your goal is to defeat the vanguard of the Serpent. Most of your tasks are the result of summoning the Worthy; their instructions are displayed on the dot matrix.
The Infinity Gauntlet deals with Thanos and Mistress Death. Your job is to impress the Mistress while dealing with Thanos. This is easily Zen's most practically unrealistic table, but it's interesting because of the reality-warping effects induced in Infinity Gem mode.
World War Hulk is all about vengeance. Bruce Banner's wife and child are dead and he himself has been shot into space. So yes, our green anti-hero is mad as hell. So he must assemble the Warbound group and do some punishing. It's a great table full of smartly designed ramps and tasks; it even includes an incredibly bizarre detour onto a basketball court.
