Types of aliens
There are three kinds of aliens encountered in the series: those who can pass themselves off as humans or human creations, those that can pass themselves off as statues and other inanimate objects, and those who can't pass themselves of as anything.
Scoring System
The scoring of the aliens seems based on how difficult they are, how they were defeated and upon who actually finished the alien off. Shooting an alien with a Y-gun gets you three points in the earlier mission and shooting it with an X-gun or X-shotgun gets you five points.
Trivia
- Most aliens are assumed to have their own names, languages and culture, this is however hardly explored over the course of the series.
