From Beteo Games:

Acamar Rising is a 3D space shooter where a lone fighter must defend a space station against the many threats of space, from asteroids to aliens.

The fighter pilot who defends the station may be lone, but he isnt without some hefty resources at his disposal. With four power-ups to be found in asteroids and 8 different weapons to purchase, the defending ship will go from bucket of bolts to deadly as sin faster than you can say hyperdrive, and he is going to need it.

Assaulting the station is a variety of threats, the most common of which are asteroids and comets, which hurtle towards the station. Let too many of these items past and there wont be anywhere to left to dock! Also alien crafts will continuously assault and harass the defenses, along with the occasional mother ship.
