Ultimate Flash Sonic Summary

Ultimate Flash Sonic is a fan-made Sonic game for web browsers that runs on Adobe Flash. Initially releasing on Newgrounds in 2004, Ultimate Flash Sonic is now hosted on multiple websites. The title is actually one of several fan-made web-based games featuring Sonic the Hedgehog. It uses many of the same sprites and other assets from Sonic Advance on Game Boy Advance.

Players control Sonic using the arrow keys and spacebar on the keyboard, with the arrow keys moving Sonic and the spacebar handling all other actions. In addition to using many of the same graphical assets from Sonic Advance, the title features very similar gameplay to the Game Boy Advance Sonic titles.

Ultimate Flash Sonic Premise

Ultimate Flash Sonic for web browser

The basic premise of Ultimate Flash Sonic is essentially identical to all other 2D Sonic games. Players control Sonic or one of his allies as they move from left to right on a scrolling screen. As players move from left to right they collect rings and maneuver through obstacles. Due to Sonic’s speed, there’s much more verticality and variety in the platforms players navigate. In addition to several enemies placed throughout the level, there are also environmental hazards. Running into an enemy without attacking it or falling into one of these environmental hazards causes Sonic to lose his rings. If Sonic gets hit again after losing his rings, he will lose a life. Losing all of your available lives results in a Game Over.

Players attempt to stop Dr. Robotnik and his evil robot army as either Sonic or one of his many companions. Each of Sonic’s companions has their own special abilities and unique move set that differentiate them from the blue hedgehog. Levels are instead “Zones” and are typically different kinds of fantastic locations or environments. Within these Zones, players make their way through 2 or 3 stages or “Acts”. At the end of the final Act in each Zone, players face off against a robotic boss created by Dr. Robotnik.
