HOW TO PLAY IT

Key timing: Shipyard by 1:56

  1. Open 3 mex, then send com to sea to build Shipyard by 1:56.
  2. Add tidal generators, wind and more mex to fund the shipyard.
  3. Pump Riptide first, then Oppressor to contest enemy sea entry.
  4. Get T2 constructor out to start scaling the naval economy.
  5. Transition into Advanced Metal Extractor as the economy phase begins.

WHAT THE NUMBERS SAY

Standard Beach sea play has the lowest team win rate of these builds and destroys far less enemy metal early than it loses eco time.

  • + Metal produced climbs to 24945 by 15:00, the highest of all six roles.
  • + Riptide and Oppressor together make 63% of army, a focused naval composition.
  • − Enemy metal destroyed is only 200 by 5:00, barely contesting early sea.
  • − T2 factory only reached in 35% of games, behind other roles' T2 timing.
