To get New Game+, you must complete the game by defeating Lavos through the Black Omen. After the game ends, reset to get the Game+ option to appear. When you choose "New Game+", you will be asked which save file you want to start with. Choose one of the three files and the game will start from the beginning. You will start the game at the same level, and with all of your spells and items that you had before. This option lets you play through to get each of the ten different endings. In a New Game+, a teleport (the Lavos Gate) directly to Lavos will appear in the right telepod of Lucca's invention at Leene Square. Depending upon when you enter this gate and defeat Lavos, you will get different endings
