How to Play Megami Tensei Gaiden - Last Bible
Quick start
Start a new story, name the human characters and use A to talk or inspect. SELECT opens the field menu: check equipment and save through System. In battle try conversation with a suitable party member rather than defeating every beast. Before confirming a fusion, read the resulting creature and keep useful healers available.
Controls
D-pad moves and selects commands. A talks, examines, confirms and advances messages; B cancels. SELECT opens the field command window and switches hiragana/katakana during name entry. START begins a linked match. Save from SELECT → System → Save; fusion is the companion’s Conback spell, which selects two beasts and asks you to confirm the result.
Megami Tensei Gaiden - Last Bible — About this game
Explore a fantasy world with three human characters and beasts recruited through conversation. Encounters offer more than combat: different party members can negotiate, and allied beasts can speak to others of their kind. Fuse two recruits into a new creature, arrange the party and balance equipment with healing magic. Field commands also provide three save files, while a cable mode pits chosen members against another player. Start a new story, name the human characters and use A to talk or inspect. SELECT opens the field menu: check equipment and save through System. In battle try conversation with a suitable party member rather than defeating every beast. Before confirming a fusion, read the resulting creature and keep useful healers available.
