Duper Mario Bros.: Koopaling Khaos is a fan game made for the Wii Y by Endgame Enterprises. This game takes the events after Coin Chaos, Mario thinks what he should do with all the coins he collected. However the Koopalings that Mario previously defeated, steals the coins and turns them into Dark Coins, well some of them. Mario goes on a quest to get his coins back.
The gameplays hasn't really changed since the prequel, but there is a Sight Meter. If you are looking at something that is very bright, you lose 1/7 of the meter. Lose all the meter bars and you'll be stunned for a few seconds. There is also a Fear Meter, Hunger Meter and Thrist Meter.
