The game mechanics is very simple: you control the main character (although you can unblock others) as he runs through 2-dimensional scenes, and you'll have to make sure to avoid all of the obstacles in the city that stand in your way, all the while battling your enemies.
In order to combat all of your enemies you'll be able to use different weapons, such as shurikens, swords, and special hits. Possible moves will depend on which character you are playing.
In terms of graphics, Krrish 3: The Game is spectacular, with some very detailed character models and scenes with which you can really interact.
Krrish 3: The Game is a very fun action platform game with great graphics that you'll want to play again and again. A great game for a great movie.
