How to unlock the Fort Knox achievement in Temple Run 2 - Definitive Guide
These achievements are tied to the objectives for collecting 500 and 5,000 coins in a single run. See "The Spartan" for more information on objectives. This is probably the most challenging achievement in the game obtain, but it is really not that difficult considering you can use as many Save Me continues as you want when you die (if you have the gems to do so). Just collect as many coins as you can but also be weary to not take unnecessary risks causing death. You will likely need to survive to 25,000+ meters distance traveled (half of that if you bought the x2 coins permanent boost from the store). For this specific achievement, it would be helpful to buy the upgrades for the boost that lowers the number of gems need to use Save Me continues.
See the Cheap Trick for the Tougher Achievements section at the end of the RoadMap for a very easy method to earn this achievement using no gems.
