You probably won't be at all surprised to find that Night at the Museum 2 has its own video game. The capers of Ben Stiller (Larry Daley, for our purposes) as he careens around a museum populated by historical figures is the stuff good family games are made of. So it is that we get Night at the Museum: Battle of the Smithsonian.
Larry has discovered that many of his favourite exhibits from the New York's Museum of Natural History which include some of his best pals have been shipped off to the archives at the Smithsonian. That's bad news, but it's not world-ending stuff. Except... Larry receives a call for help from Jedediah, the miniature cowboy, telling him that Kahmunrah and a triad of heinous (and rather notorious) henchmen - namely Ivan the Terrible, Napoleon and Al Capone are taking over the museum with an eye toward the entire world.
Gameplay in the DS version takes the form of a sidescrolling platformer. Players run, jump and dodge their way through the museum, which has come alive thanks to its rather animated exhibits. The twist is that players can use the DS touch screen to activate different abilities in real time. Players cling to walls, super jump, fly, shrink, charge and stomp their way through the game, using Larry's trusty flashlight and key chain to navigate through the Smithsonian.
