Defenders of Oasis is a role-playing video game developed and published by Sega for the Game Gear in 1992. The game's setting is based on One Thousand and One Nights, and the plot centers on a heroic prince and his companions, who set out to confront an empire attempting to revive the dark god Ahriman. The game was one of the few original RPGs made for the Game Gear, and features an overhead gameplay perspective, a command-based combat system, and an autosave feature. Defenders of Oasis was commercially successful and positively received by reviewers, who praised the game's visuals and level of detail.

Each village includes at least one shop where the player can purchase and sell items that can aid the Prince and his party, such as weapons, armor, and accessories. Villages also include a certain place where the party can rest and recover their hit points and spell points.

As the player characters take damage from enemy attacks, their number of hit points decreases. If a character's hit points are fully depleted, the character will be knocked out and unable to fight unless another character uses an item or spell to revive them; characters who are knocked out will also revive with a small number of hit points if the battle is won.
