Just an old fashioned Spy and Fly.

Not the biggest hit, the most profit or my best ratio
- I tried to send an appropriate amount of War ships and it looked great on paper. The ratio isn't bad either, but this guy was pretty turtled in, explaining why the profit was not that great.

Either way, here is how it went...

The attacker has won the battle !
You receive 289031 units of Metal, 718334 units of Crystal and 123883 units of Deuterium.
The attacker has lost a total of 24.130.000 units.
The defender has lost a total of 121.379.100 units.
A debris field containing 32.517.210 units of Metal and 16.418.850 units of Crystal has formed in orbit around the planet.
The probability of creating a moon is : 20 %

No moon

Still, more fun than farming and a nice little profit at the end.

Good luck on the Rebuild Cragen!
