If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
Drive a train and rush to reach the end of the level in the quickest time possible. Use your NoS power to achieve your goal, but there is also a twist: you will have to pick up passengers from the train station and transpot them safely until the next one. Collect coins and extra NoS on the way and try to get a high score. Make sure your passengers still have some health remaining when reaching the end. There are eight incredible levels available for you to enjoy. Have fun!
