From Realm of the Titans Wiki
The achievement system in Realm of the Titans is meant to be used as a way to show off your accomplishments. These accomplishments vary in difficulty from adding a friend to your friends list, to achievments that require a high skill level with certain heroes.
One tangible benefit of the Achievement system is unlockable titles that are displayed at the loading screen and above your character in game. These titles let other players know that you mean business when playing against you.
|Achievement Name||How to Achieve||Reward|
|Ultimate Titan||Reach a killstreak of 10 or more in 10 matchmaking matches||Ultimate Titan title|
