Zero-K is a simple game. All you have to do is:	
 - Keep your constructors tasked at all times
 - Relentlessly expand to build more metal extractors
 - Build more energy to match your metal income
 - Build more buildpower to match your metal income
 - Build radar everywhere so you have vision over the map
 - Build defense towers in threatened locations
 - Don't overbuild defenses where they're not needed	
 - Watch the strategic map
 - Know where the visible enemies are
 - Guess where the non-visible enemies are
 - Know or guess what the enemy unit composition is
 - Change your factory orders to build the appropriate counter-composition	
 - Know where your units are and what they are doing at all times
 - Keep your army in motion
 - Attack ruthlessly where you have the advantage
 - Retreat hastily where you are at a disadvantage
 - Send the right army composition against the enemy composition
 - Micromanage individual battles so that:
    - Riots attack raiders
    - Skirmishers attack riots
    - Raiders attack skirmishers
    - Assaults and artillery attack defenses
    - Everyone attacks constructors and economy	
 - Scout early to spot an all-or-nothing play
 - Scout often to see when enemy plans are changing
 - Build the appropriate counters to whatever plan is afoot
 - Be prepared for an enemy switch to air
 - Build air defense as soon as it is needed, but no sooner
 - Switch to air when the enemy gives you breathing room
 - Don't switch to air once he builds air defense	
 - Send constructors to reclaim wrecks after winning battles
 - Build more constructors to expand faster
 - Build more constructors to reclaim faster
 - Build more constructors to replace the ones you lose
 - Rebuild metal extractors when you lose them
 - Keep building more energy to overdrive your metal extractors
Do all of the above simultaneously and you'll be victorious! Nothin' to it.
