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.
