This game does not take long at all if your skilled and have the patience to go through the Forest of Death Exam with every character and win 5 times in a row with each them as well as finding all the Coins in the game which will be discussed in depth in the Introduction.

Introduction:
Naruto: Rise of a Ninja is the first RPG based Naruto game to hit the new generation consoles. However the fighting system isn't the best around compared to the Playstation titles. Every offline achievement can easily be unlocked as most of them are story related anyway.

The online achievements however will take some time depending on how skilled and patient you are trying to get the achievements. The achievements aren't as hard as they would be before Broken Bond came out.

Also keep in mind that having Shikamaru downloaded could freeze you game at certain points when you hit traps so leave him deleted for the time being until you reach Step#3

Step 1: Main Story Mode
When starting your story mode, DO NOT collect any ancient coins at all during your playthrough , you will however be required to get 12 coins throughout the story to proceed, if you do somehow accidentally run into any coins, refer to the maps on the Coin Maps link to cross it off the map of coin locations. The main story does not take long if you're skipping mini games and side missions (which will be done anyway in Step 2). Focus on breezing through the story and getting all of Naruto's level 3 jutsu's

Step 2: Mop Up
This will be a long step into your journey, now that you have an upgraded Naruto you can be track and finish any achievement you might have somehow missed in the Main Story (like The Untouchable Ninja and other misc achievements like that) and start on all the mini game achievements of the game. A Map of the Lovelorn achievement can be found in the guide. Once you are done with every mini game achievement you should have your Leaf Village Hero Achievement by now seeing as you helped everyone with your side missions. Now if you followed directions you should only have 12 ancient coins from Step 1 for when you go Coin Hunting, refer to the Coin Maps link for directions.

Step 3: Forest of Death Exam
This could possibly be the hardest of task in the game, to win 5 times in a row with each character. Refer to the hints in the Naruto Online Battle tips link and if your planning on boosting the game instead of doing it legit (boosting is highly recommended for faster results) then refer to the Naruto Online Boosting Method.

Also at the moment, the 4 DLC characters from the Marketplace have glitched achievements that cannot be unlocked, so don't waste your Microsoft points until it is patched. Shikamaru's achievement was patched allowing you to reach 1015 right now.

Conclusion:
Though this game doesn't take long at all, most players give up after Step 2; but if you're a true a completionist then take the time to attempt the Forest of Death with all the characters for an easy 1000 (or 1015 with the free Shikarmaru DLC)
