Music and levels are designed amazingly well. Some random characters will show up during a playthrough, which is fun. What’s really cool about it is the ability to select from 5 different characters in the options including Metal Sonic, Sonic, Kirby, Tails, and Draken. Metal Sonic Overdrive is the older version of Hyperdrive. About 20 minutes of pure fun and random craziness! – Information and Download It’s also the only Sonic hack to have a heavy emphasis on story dialog. The game is fun, fast, action-packed with enemies and explosions. I wish it was longer! – Information and Downloadīasically is what a Sonic Game made by Michael Bay would look like, lol. The speed of this game is so fast, I did not expect this game to turn up the heat so quickly. Music, level design, action, unique boss and sonic graphics changes are all awesome. Sonic Boom is short (About 10 to 20 minutes long) but full of action-packed sweetness. It’s a full-fledged game taking around 23 minutes plus to beat, So I have to give the Developer a lot of credit. The gameplay has a nice flow to it, because of the decent level design. Sonic Netinirvana is pretty neat, features all new levels, some new music, and color pallets.
