Granada is a free-roaming scrolling shooter set in Africa where war has broken out over mining rights to rare metal. A mysterious maneuver cepter called "Granada" has appeared, destroying the weapons of both factions, and you play as its pilot, Leon Todo.
Granada features a map that guides you through each stage, where your target is highlighted, followed by a large boss enemy that must be destroyed after all targets are eliminated. You can choose between a standard cannon and a powerful blaster, which will also push your machine backwards with recoil.
The game includes assist pickups that follow you and reflect incoming shots towards enemies. A unique feature of the game is the fixed cannon, allowing you to hold fire while moving freely. Granada has nine stages and three difficulty levels.
