Welcome to the help section. There are FAQ sections covering Technical, Gameplay and Mission Play - Acts 0 to 1 and 2 to 3.
Credit for these pages go to members of the ina-community forum and Particle Systems. A special thank you to Parias.
If you can't find your answers here, try asking in the forums.
Note: You should read these pages in conjunction with the Acts (walkabout) pages.
WARNING SPOILERS: Be careful how you read these questions. Some will give you answers to missions you have not yet reached.
