Got hard badge on Campaign(normal mode): 2xlasers(max), 1xgenerator(max), wall(max), supa dupa machine gun(max). Rest into gunmen(125) and repairmen(64). Easy.
For all those ppl asking why they reached day 40 on the campaign and didn't get the points. Maybe u chose 'easy' mode and that's the prob. Was the same issue with me. On normal mode i got the points.
