Anthem

8-bit Anthem theme
At the main menu, press Up(2), Down(2), Left, Right, Left, Right, Circle, X to change the music on the main menu to an 8-bit version.

Special damage bonus
Simply unequip all Support items to get a +20% to +25% increase in melee, combo, and special ability damage. Note: You can only unequip items by creating a new custom loadout. The more weapons you have equipped, the less damage you do in the game's current state. Equipping Masterworks will also lower your total. Thus, if you only equip Legendary gear, and only take one Legendary weapon with you on missions, you will increase your damage output even further. Additionally, it is likely this trick will eventually get patched.

Easy high level loot
Simply start the first Stronghold mission, collect the first chest, and then quit the mission. Repeat this as many times as desired. Note: This trick may eventually get patched.
