Like I've mentioned, each of the three characters has different skills to advance. The Human has melee combat, ranged combat, rigging skill, and life. The Gladiator can also advance in melee and ranged combat, but was also blessed with the override skill. Last but not least, the Culibine (the last of its kind), a very expensive character to maintain; if you play as the Culibine you can improve ranged combat, focus and radial skills (which help the character to improve his competence with unique energy weapons). This sounds all well and good, but somehow when you play, these skills don't seem to help you overcome any real challenge, and so I guess this way the game loses a lot of its RPG charm. Another slightly disappointing RPG aspect is that the player doesn't get to advance any skills that would allow him to use other weapons besides those he uses by default. All in all, it should've been a lot more complex.​
