When the Riddler escapes from Arkham Asylum the Dynamic Duo discover he has a museum in his sights. But the Riddler’s riddles reveal he does’t just steal from the museum, he actually makes off with the whole thing. With the help of World War era decoding machines the Riddler takes command of the Gotham City Military Museum, a fully functional battleship. Now it’s up to Batman and Robin to spoil his plans before he blows Wayne Manor and the rest of Gotham City out of the water.
