HOW TO PLAY IT

Key timing: Shipyard by 3:16

  1. Grab 3 mex and open wind while laying down bot lab.
  2. Get bot lab up then push straight into shipyard.
  3. Finish shipyard, start pumping subs and frigates to contest sea.
  4. Add submarine, frigate and destroyer to hold sea lanes.
  5. Bring geo online and transition into mixed navy.
