Specter of Laplace
The Earth Federation and ECOAS execute their assault on Palau, with the intention of rescuing Banagher and the Unicorn. Saboteurs destroy Palau's connecting bridges, while the Nahel Argama unleashes its Hyper-Mega Particle Cannon, pushing the asteroids towards each other to damage much of the Sleeves' forces. Any Sleeves unit getting out is ambushed by ECOAS units hiding in the rocks.
