Crush, Crumble and Chomp!

Crush, Crumble and Chomp! was a turn-based action game played on a scrolling 2D grid-based map. The game engine was written in BASIC and used character graphics for the map and player, using basic graphics on platforms that supported it. On the Atari 8-bit family, for instance, the map was created out of a custom character set and presented in a low-resolution mode that allowed up to four colors. The same engine was used in most of Epyx's games from the early 1980s, which allowed them to be ported to a variety of home computer platforms with ease.

The game allows the player to recreate a movie monster and attack a city, much in the manner of the classic horror movies of the 1950s. Specifically, the player can create:

Goshilla, a giant amphibian like Godzilla, with a breath and leaving a corrosive trail of radioactive waste.
The Kraken, a giant octopus or squid-like monster, that can attack bridges and seaside ports and then slip into the water to hide from attack.
Arachnis, a giant spider, can clog roads with its web and can escape underground via its network of secret tunnels.
The Glob, akin to the monster in The Blob, can travel underground in the city's sewer and absorb obstacles in its path, including skyscrapers. It also leaves a flammable trail of slime in its wake.
Mechismo, a towering robotic menace, sports an exotic array of alien weaponry, such as ray guns.
Mantra, a giant flying monster, like the infamous Mothra
Space Jockey, a large extraterrestrial with sharp claws and acidic breath

The game also allows the player to "grow" their own monster, with custom abilities they choose. When doing this, the player is given 120 "crunch credits" to spend. Each ability costs a certain number of credits. For example, the ability to "leap tall buildings in a single bound" costs 8 crunch credits. The player can add a number of abilities until their credits are exhausted.

Crush, Crumble and Chomp! features four cities to attack: San Francisco, New York, Washington DC and Tokyo. Combined with five possible objectives and the six (or numerous ones, counting the custom) monsters, this game has robust replay-ability. After attacking a city—the main activity of the game—players are rated on how well they did. Players are rated even if their monsters die in the attack and can achieve a high score for what they accomplished before expiring.
