Q: I just bought nanos. What should I spend them on?
A. That really depends on your level. Some units that are very useful at lower levels become obsolete at high levels. The best units at the highest levels are Mega Tanks, Elemental Troopers, and Veterans.To help you, please see the Unit Reviews section of this Wiki.
You can never go wrong with resources at any level, including advanced mines and advanced mills. An advanced hospital and repair bay may seem expensive, but will cut healing costs and time by one-third at its highest levels.
At level 40, an investment in High Capacity Vaults is always recommended.
Of the nano shops, the Home Defense Expo gives you the best bang for your buck.
Q. How do I unfriend someone?
A. Click on your name in the top left, go to the friend list, find the person in the alphabetical search, and click on the red minus sign.

Q.What is "Battle Resources Earned" in the leaderboards?
A. From redrocker7 on the forums:
Battle resources earned is the sum total of ALL resources earned through occupation, raiding, battle rewards, PvP and production. They include: gears, bars, teeth, skulls, chemical vials, widgets, laurels, necklaces and powder. Something rarely discussed is that since the hard storage cap regime was harshly instituted was how this has really made it hard to collect and earn battle resources sufficient to move up the leader board, unless you are in a guild that doesn't mind exploiting a few as yet unpatched 'glitches'.
