This game has many achievements, unlockables, and endings for you to go for. This remaster is meant to make the game more playable, and just like in Forever, you can customize the game look and feel the way you want it to be.
Sonic.EXE Forever is the way to play the original Sonic.EXE, Sally.EXE, and Round2.EXE, all 3 games, in the style of Sonic Forever.
