The game is inspired by Rockstar Games' Grand Theft Auto games, in that the player can complete a variety of missions within an enormous city that is open to explore. During development, around 50 story missions and 30 challenge levels were planned. Gameplay elements shared with GTA include the vast assortment of weaponry, the miscellaneous shops, the ability to hijack vehicles, and the ability to attract police attention with violence and destruction.
As a homage to numerous 8-bit video games, Retro City Rampage incorporates design elements from many different genres, and features 16 graphical filters that simulate various retro computers and game consoles. Although it is primarily played from a top-down bird's-eye viewpoint, in specific sections, it may switch to a strictly two-dimensional perspective in the style of a 2D platformer.
The game also includes a "Free Roaming Mode" that allows players to freely explore the city and cause as much chaos as they can. This mode can also be played with unlockable characters from other indie developed games: like Super Meat Boy, Commander Video from the Bit.Trip series, and Steve from Minecraft, among others.
On February 28, the same day as the Wii release, an update for PC became available, allowing users to access a version of the game's prototype, called ROM City Rampage. ROM City Rampage is a port of Retro City Rampage to NES homebrew and emulated within Retro City Rampage. PC users received the update for free, and it was included with the Wii and 3DS versions. The update was later released on PSN and Xbox Live.
Development
The concept for Retro City Rampage originally came from a homebrew project that began in 2002. In his spare time, game programmer Brian Provinciano constructed his own Nintendo Entertainment System development kit and set about remaking one of his favourite titles, Grand Theft Auto III, with 8-bit sprite graphics, under the codename of 'Grand Theftendo'. At the 2011 Game Developers Conference, he revealed his methods, showing how, over several years, he built advanced software tools to help him overcome the limitations of Nintendo Entertainment System hardware, before eventually shifting development to the PC.
At one point in the process, he started to add characters and locations from other games he enjoyed from his childhood. This ultimately inspired him to work on the project full-time, but instead of using scenarios from GTA III, he decided to create an entirely new game with original content in 2007, which would be released as a downloadable title for consoles. He used a real-time map editor to adjust and debug on the fly, and also integrated several suggestions from playtesters.
For most of the project, he had worked completely independently on the design, coding and art. Later in development, he hired a pixel artist to assist with the visual design of the game and went through revisions. He also brought in three renowned videogame composers, Leonard "FreakyDNA" Paul, Jake "Virt" Kaufman and Matt "Norrin Radd" Creamer, to create chiptune songs for the game's soundtrack. Provinciano stated that the game contains roughly two and a half hours of chiptune music. On February 22, 2012, the Retro City Rampage soundtrack was released on Bandcamp.
The game pays tribute to many titles through its title, storytelling, levels, and character abilities, such as River City Ransom, Super Mario Bros., The Legend of Zelda, Duck Hunt, Mega Man, Contra, Bionic Commando, Metal Gear, Smash TV, and Teenage Mutant Ninja Turtles, among others. The game also pays tribute to "cheesy" one-liners, television shows and pop culture, as well as cameos including Phil Fish (creator of Fez), Billy Campbell, and Phil Guerrero (of YTV fame) with permission.
Despite the game's title sounding similar to River City Ransom, Vblank Entertainment's Retro City Rampage Twitter account has stated that the title is, in fact, not a reference to River City Ransom.
The game has received several updates since the original release polishing the game and adding features. The PC version specifically has been updated 15 times.
Reception
Retro City Rampage has received positive reviews. It holds a metascore of 71 on Metacritic.
As of March 2013, the game had sold around 100,000 copies. PS3 and PC versions made the most profit, 360 version the third most, and Wii came last with about 2500 units sold.
As of December 2014, the developer announced the game had reached 400,000 sold copies (and an additional 270,000 PS+ units) while also revealing that the PC and the PlayStation family versions were the most successful.
Sequel
On November 24, 2015, Shakedown: Hawaii, a sequel to Retro City Rampage, was announced.
