You need a lot of MP in the Road Warrior game if you want to unlock the best cars, and free MP is always my favorite.
Luckily there are several ways to get free MP in the game, if you’re patient enough to do them.
Free MP From Promoted Videos
Every promoted video that you watch gives you 10 free MP. You’ll have the opportunity to watch a video after every single player race, or you can get to them by hitting the blue Add button on the garage, then clicking the blue Free MP button at the top right of that screen, and click on the Promoted Videos button.
There is some sort of hidden timer that will keep you from watching too many promoted videos at back to back, so don’t expect to sit and watch hours of promoted videos straight through.
Free MP From Downloading Apps
Tap the blue Add button in the Garage, then hit the blue Free MP button in the top right of that screen. You’ll see a list of apps and games that you can download to get a set amount of free MP.
Make sure you read the instructions below the app or game to see how you get credit for the download though. Some of them you just have to download and start, others you have to reach a certain level or enter an email to sign up, etc. Some also require that you’re 18 years or older, so always pay attention to the requirements.
Free MP From Racing in Multiplayer
Racing in online multiplayer matches is another way to get free MP. Placing in the top three will get you some free MP, but it’s not a very large amount. This is probably the slowest method to use, but it doesn’t really require much effort if you’re already playing in multiplayer races anyway.
