This guide if you like was made using a few guides I saw here and there, plus my own knowledge. I noticed there was not one single side quest guide so here is a complete one.
The side quests from the original game (so the first three Acts) were taken from here, so all credits to Zenpo for his fantastic work there. Also, credits to Gamebanshee for being an awesome, awesome place and having screenshots of the map.
NOTE: The directions (North, South, East, West etc) are taken not from the direction of the player but from the direction OF THE MAP. If you are unsure, check the map.
NOTE: If I am incorrect anywhere, please comment and I will change.
NOTE: Anytime you see the exclamation mark above a persons head go gray, it means youve spoken to them enough. If it is still yellow, TALK TO THEM AGAIN! Some people require you to talk to them several times.
NOTE: If you dont have the Fanpatch and complete a quest with a reward that requires the Fanpatch, have no fear. When you download the Fanpatch, talk to the man next to the Helos Portal and he will give you all your missed rewards.
NOTE: If you require any further information about a quest, or youre lost; just reply to the thread and Im sure either I or any of the other Forumers will help you out!
