Hellbender is a simulation video game developed by Terminal Reality and published by Microsoft Studios for Windows 95.

The player is in control of a prototype spacecraft (the "Hellbender") and must fly it around a map, destroying various targets and reaching checkpoints.

The Valkyrie and Laser cannons have unlimited ammo, but there are also dumbfire Sledgehammer rockets, homing Viper missiles, and devastating Doomsday mines.

[3] The player's character ("the Councilor") is the last surviving pilot for the Coalition of Independent Planets, the defense group that protects the universe from the Bions.

The pilot must accomplish various objectives on eight different worlds in order to stop the Bions, save the universe, and win the game.
