Technique: 100/100 (5)

Start by building a couple of Infantry units with Grit.

Focus on building Rocket units to take out the front cannons.

For Drake, avoid building units on the first turn. On the second turn, build Subs and sacrifice them to gain the tsunami effect, which halves fuel and hinders enemy submarines and tanks.

(Optional: You can repeat the tsunami tactic later. Move units into range of the Black Cannons; they never die, and your CO power will increase. The enemy will eventually run out of fuel just outside the outer ring of piping.)

Begin building B-ships and move them up the left side to destroy lasers and rockets. Do not destroy the lasers until you have approximately 6-8 Grit-rockets ready near the exit.

Andy's role is to handle the right-hand side navy, the right-side laser, and act as a decoy.

Build a Battleship to move up the right side and destroy the laser.

After the laser is down, build Neotanks and Bombers.

When Sturm appears to be preparing his Meteor Strike, group your units together so he hits them instead of Grit's rockets.

Use Sturm's CO power and cities to repair all your units and prepare for the Meteor Strike.

To finish, after luring out and destroying enemy units (either with Drake's B-ships off the west coast or Grit's Rockets from the center), move all your rockets (aim for about 8 for Grit, plus any extras from other COs if you had sufficient funds) to the outer pipe.

Use bombers and Neotanks as decoys for the Black Cannons.

Once each opening is blocked by 2 rockets, use Grit's Super Snipe (ensure you saved his CO power) to destroy all Black Cannons in a single turn.
