dev2.5 base defence missions

[jcjordan]

What are the triggers for aliens to start attacking bases & how do you minimize the aliens ablity to find/attack your bases or stop it from happening so soon in game? I've had 2 new campaigns w/ Dec downloads that the Aliens just seem to go nutzo after my bases early in the game (2-4 attacks each month at my 2 main bases) using Harvesters which I don't have anything that can shootdown one yet so that isn't an option to contain them. Having this many base defense missions & trying to go on others leads to way too many WIA/KIA leaving no healing time. IIRC missions pace were supposed to go down to allow some downtime but the pace of these past 2 campaigns has been greater.

Any ideas on how to go deeper underground?

Aliens have interest in different areas (mission types). Success or failure of them may increase or decrease their interest in other missions. Hiding a base is not really possible, sooner or later they will find them, you can build batteries or SAM sites to keep them away from your bases though.
