More Brain Age to keep your brain young and fit.

The game that launched a new generation of gamers is back. Based on the theories of neuroscientist Dr. Kawashima, Brain Age 2: More Training in Minutes a Day contains all-new activities to challenge a player's gray matter.

The title is a series of trainings designed to give the brain a workout. The 17 new, engaging activities are all designed to help work the brain. Whether players are playing simple songs on a piano keyboard or monitoring the photo finish of a footrace, they'll love this new mental workout.

When starting a new game, players take a series of tests and get a score that shows how old their brain is. This number is called the "DS Brain Age." With daily training over weeks and months, players strive to improve their mental acuity and lower their "DS Brain Age." Progress is charted in graph form.

Players can keep up to four save files on one game card. Sharing a game allows players to engage in a picture-drawing quiz or other challenges with family and friends. Players also can use DS Download Play to send a demo to friends or compete with up to 16 players in one of four fun modes.

How to progress through the game: When starting a new game, players will be given a Brain Age Check that determines their DS Brain Age. Each day, players can compete for the high score in any activities that they have unlocked. They also can record the age of their brain once per day. The more players train, the more activities they will unlock. The title is designed to be played in small chunks over a long period of time.

Special powers/weapons/moves/features: Players who play wirelessly with friends or have multiple people playing on one game card can compare scores or rank other people's creative efforts. Solo players also can unlock a mode called Virus Buster, which is a new take on the Nintendo classic Dr. Mario (to relax the brain after the training).
