Sonic Battle is a pseudo-fighting game, akin to Super Smash Bros. from Nintendo. Rather than being 3D side-scrolling, this game employs a 3D isometric view – not a static, sprite-based field though, it is comprised of actual texture-mapped polygons. The character sprites are 2D though, and while you think it wouldn't work – it does.
dekutony doesn't even break a sweat and completes Challenge Mode as Shadow in record time.
