Rampart is a tower defense video game from 1990, released on many plaforms including the SNES. Along with the 2/3 player battle modes, the SNES game also contained a more expansive single player campaign with just under 50 levels. The game follows a 3-phase system: battle → repair → place cannons → battle. Failing to build a wall around a castle results in losing a life, where destroying all enemy ships completes the level.

In this TAS, Natetheman223 aims to cover as much land as possible, while having fun by making some cool designs, and pretty much making a fool out of the enemy ships.
