The lights are on
This is my first stab at a guide, I've read quite a few and will just keep it plain and simple in a point by point format. Please note that the majority of the Achievements are awarded at the end of the game, if you leave mid-game and should earn an achievement you should be awarded it at the end of the next game, but may have to do something related to that achievement to earn it. So, let's get right into it!
Combined Achievements: These can be earned by Campaign and Classic
Hope this guide helped somewhat! Most of the achievements are fairly self explanatory, but some do require a little bit of logical thinking with strategy. Hope you all are enjoying the game as much as me! Good luck and happy achievement hunting!
