In Diablo I, the town of Tristram has a problem. Diablo (the Devil) is trying to release hell from underneath the town church. You must battle your down through the church, through the Earth itself to finish this fight and save Tristram. The goal is to find, kill, and trap Diablo's "soul" back in his Soul Stone.

Diablo II: The Hero from Diablo I was a little over confident, and believes he can control Diablo's soul. Diablo soon begins to over power him and sends him on a quest East, to find his brothers, Mephisto & Baal, and bring Hell to Earth.

In Diablo II, you race after Diablo (aka the Dark Wonderer) as he raises Armies from Hell and Terrorizes the land looking for his brothers.

This game type is where you look down at your character. Using the mouse and the keyboard, you can melee and cast spells to protect the world over-run once again by Diablo.

Diablo, Diablo II, and soon to be Diablo III. Both 1 and 2 have expansion packs, which are a must. Well worth the extra cost.
