|Thundercats: The Lost Eye of Thundera Video Game is a side scrolling video game published in 1987 by Elite Systems for home computers including Amstrad CPC, Amiga, Atari ST, Commodore 64 and ZX Spectrum.
When the game begins, the player is shown an image of Mumm-Ra, the Thundercats’ main villain, and is told that Mumm-Ra now has the Eye of Thundera, the source of the Thundercats’ power.

The fourteenth and final level of the game is nearly twice as long as all previous levels. The player is given a larger time limit to complete the level.
