The database was made to help players learn the basics of Alien Invasion, city raids, APF raids, ranks as well as other related information that could be accessed easily in-game.
It was due for an update, since I've been in many raids in my clan's city and at apf there are things I've learned that are MUST READ to players with the AI expansion.
Part of it is information about Sector 42 in apf, new tactics for raiding, and a bit more info on the aliens.
This will probably be the final version of my database, but if I learn any new tips, tricks or tactics I will certainly update it.
