Descent (PSX)

Hints:
* Always keep moving. If you sit still, the robots will tear you apart.

* Use your side buttons as much as possible to avoid enemy fire. Sliding left
or right at the last moment will cause missiles (even homing, smart and mega
missiles) to miss you.

* Find the exit before you blow the reactor. The way out is not always the
way you came in.

* Clear out your exit path before blowing the reactor. Time is tight when
you're trying to get away. Having to duke it out can cost you precious
seconds.
