Every loop has two versions. (Except the Epic Loops, it divided into three parts, and except Emotional loop. ) One version is louder, and has more instruments, one version is quieter. This will help for you increase and decrease the tension during the gameplay.
Epic loop has three parts, an intro loop, a middle loop, and a "high tension" version. This necessary, because I don't know, what length your epic or important scene in your video game. Every parts is loopable. This might be helpful, when your epic/important scene's (or your transition video) length is not the same length, like my track's footage.
Action loops are simple fight scene loops. Boss fight loops are more monumental and epic than Action loops.
As you see, I created endings for all of the tracks, so you can close the music with this. And finally you get a simple drum loops.
