Achievements

 * Maxing out all perks for the Sentinel is one of the possible criteria for unlocking the "Tinkerer" achievement, and unlocks the "Tuned To The Max" achievement.
 * Using the Sentinel for 15 runs unlocks the "Vigorous and Versatile" achievement.
 * Down and to the left in the Sentinel's cockpit, there is a red box that has the words "Emergency Entertainment System" or "ESS" on it. This is an easter egg of some sort.
