The prows of the UNSC ships flared as their magnetic accelerator cannons fired.

Archer missiles and magnetic accelerator cannons fired in a desperate counterstrike.

No ship had yet evaded the new magnetic accelerator cannon, which could accelerate a tungsten-alloy slug to a fraction of the speed of light.

In the twilight regions on either side of the moon, magnetic accelerator cannons flared, briefly illuminating the now-split UNSC battle group in high orbit.

Then, as the range began to close even more, the quarian vessel turned on the batarians and opened fire with two magnetic accelerator cannons.

Their job this time was to get groundside and protect the generators that powered the orbiting Magnetic Accelerator Cannon platforms.
