ジャーニー
ジャーニー（Journey）はプレイヤーが好きな時に難易度を変えることができる. 他のモードと違い簡単なモードである. ジャーニーを利用するには、キャラクター作成とワールド作成の両方のメニューでJourneyを選択しなければならない.

ハードコア
Hardcore characters die permanently, and drop all of their items upon death, including coins and ammo, which other players can then collect in multiplayer.

Death causes a Hardcore character to become a Ghost that can continue to observe the world but not affect it. Ghosts can fly, pass through walls, and continue to chat with other multiplayer users, but cannot interact with the environment in any way and cannot open a world. Other players are not able to see Ghosts.

Once a dead Hardcore character quits the current world, that character is permanently deleted. Items the character placed in chests will not be deleted, but items the character had in portable storage will be deleted.

There is only one Hardcore-exclusive item, which is also Expert-exclusive:.

ワールドモード

 *  Classic ( Normal) mode: This is the regular world mode.
 *  Expert mode: Intended for experienced players, Expert mode worlds contain the same enemies, but with increased stats, and some have altered behavior patterns that make them more difficult to defeat. Loot drops are more frequent, however. As a special reward, bosses drop Treasure Bags which, in addition to the normal boss loot, also contain special items only available in Expert mode. Expert mode brings numerous other changes. See Expert Mode for a more complete list.
 * Master Mode: A harder version of Expert mode, with no new AI s but increased health and damage. It also includes 2 new drops per boss, and an extra accessory slot. See Master Mode for a more complete list.

ノート

 * In an Expert Mode or Master Mode world, enemies can steal the player's coins and despawn, which can be a tremendous setback.
 * The coins drop is rounded up.
 * Difficulty modes and world modes are unrelated to Hardmode, which is a change to the world that occurs after the Wall of Flesh has been defeated.
 * In the, Classic World mode is called "Normal Mode".
 * In the, Classic mode is called "Normal mode" and Mediumcore is called "Difficult". Hardcore is still called "hardcore".

Tips

 * Mediumcore characters may want to keep their second-best equipment in a chest in case of death.
 * Hardcore mode can be utilized to freely explore a world by dying and flying through the ground and sky as a Ghost.
