Scouting and Esionage

[DayOne]

I think instead of "espionage", "intel-gathering" could be a very good gameplay feature. As mentioned before you steal some sort or intel that make capturing a base slightly faster. Or how about installing hidden cameras in bases? Limited to only 1 or 2 per area due to "interference" but it would be pretty cool. Remember you have to actually get into bases to plant these and just a few motion sensors could foil you.

Another pretty cool feature, with all these resources and what-not, would be sabotage. Although not directly gaining the resources for yourself you effectively deny the enemy resources until it is fixed. A simple addition of long time charges or remote explosives would be perfect for this.
