New Super Mario Bros. DS - Mario vs. Luigi Multiplayer Battles (All Courses)

Co-op gameplay for all 5 multiplayer battle courses in New Super Mario Bros. for the Nintendo DS. Here the goal is to get as many stars as quickly as possible before the other player does. This includes the grassland course, the underground, the snow/ice kingdom, the land of pipes and Bowser's castle. I am Mario and my friend is playing as Luigi. I put their screen in the top-right corner, so you can see what's going on there. NSMB 100% walkthrough playlist: New Super Mario Bros. DS playlist:    • New Super Mario Bros. DS 100% Walkthrough
