There are two ways to go about this achievement, the glitch method and the legitimate method:1 - Glitch Method
Similar to "Peggle 2", this achievement can be "boosted" by deleted your game save, and then replaying the same challenges multiple times.
What this means is that you can do 30 easy challenges from the easier tracks, then delete your game save (via "My Games & Apps"), and then repeat them until you unlock the achievement. The cloud will keep track of all the challenges you complete, even if you are doing the same one over and over again.
Below are the steps to do this glitch, which will only work on Xbox One:
- Disconnect from internet
- Delete local save via "My Games & Apps"
- Complete easy challenges from some of the easier tracks in the game
- Repeat Step 2 & 3 until you've completed 119 challenges or less
- Quit Trials Fusion
- Connect to the internet
- Play Trials Fusion and "Sync Save" when asked
- Complete challenges until the achievement unlocks early
Keep in mind that this method will not change the in-game counter for challenges. It will however affect your tracker in the "Achievements" app on your Xbox One, and also be noticeable via SmartGlass. If you go over 120 while offline, the achievement will unlock when you sign back in.2 - Legitimate Method
I want to start out by saying that legitimately completing this achievement is extremely difficult. 99.9% of players will not be able to complete some of the requirements for this achievement, but if you are a good Trials rider, and have the dedication, it is possible. To get this achievement you will need to complete all 120 unique challenges available in Trials Fusion, scattered on 40 tracks. The challenges range from completing a puzzle, to beating the track in a specific way. The most difficult challenges are present in the Extreme tracks and require you to beat some of the Extreme levels with 0 faults using the Roach or Rabbit bikes. Another will require you to complete harder versions of the levels, or not be able to see your rider/bike. It is recommended that you are able to complete most of the Extreme tracks without problem before attempting these.
Now, to get to a list of sources that can help you out. Here are a list of hyperlinks with good and detailed sources of information on how to complete challenges:Track Challenges Guide (RedLynx Forum) (See "Spoiler" tag in thread)Extreme Track Challenges by BiGSH0TROB (Videos)Track Challenges by Click to Unlock (Videos)
You are free to complete the challenges in any order you want, and the achievement will unlock upon completing the final one.
