Battle Insects Den is a strategy role-playing game for the PlayStation and was released by Jaleco in 1999.

The game progresses through a series of strategy and adventure parts.

In the strategy part, the player controls an allied insect on a battle stage that resembles a chessboard, and when it comes into contact with an enemy insect, the game shifts to a command-selectable battle.

In the adventure part, the player controls the main character on the overlooking map, talking with other characters and shopping.

You can also connect your PocketStation to play mini-games and bring the items you obtain into the main game.

An insect exhibition was scheduled to be held, but the insects escaped. In order to collect them, the main character, a young boy named Shohei, sets out on an adventure.
