Sonic Battle Game Sample - GBA
Sonic Battle... a GBA brawlfest where characters from the Sonic universe duke it out in arenas by altering their abilities between Ground, Air, and Defense, and up to four people can play! It's the second Sonic fighting game, the first being Sonic Championship ( or "Sonic the Fighters"). While the game is quite simple, it's a decent game that's better with friends (due to its various multiplayer games, all but one of which are multiplayer) and looks and sounds pretty good for a GBA title.
Like more modern Sonic titles, each primary character can partake in the story mode, which is viewed from different perspectives and the game has all the staple modes necessary for a game like this such as a Battle Mode, Training Mode, and even a Challenge Mode (which is more like "Survival"). Each character has different stats and characteristics, such as Rogue who can float or Chaos who is very heavy. Each character's bread-and-butter consists of a simple combo one button, the ability to chase knocked back opponents and hit them and/or use a special skill with another button; it never really changes. They can also heal and raise their "Ichikoro" gauge (which when full allows a character to instantly K.O. with a special attack).
This is a video showing some stuff in the game. Enjoy.
