Chaos Faction 2 is in some ways both superior and inferior to the original game. While it is neat to see a more "refined" art-style, the dozens of new weapons and characters, and the new hectic stages, sometimes the hazards end up resulting in dozens of cheap deaths.
In addition, unlike in the first game, there is no way to tell how much ammo you have left with your weapon, so you have to guess. There is still no way to tell how much health you have in a team battle, and despite Gorilli, Mechalo and Vortigon's return, Cowboy (the third wheel) is inexplicably missing, and his presence is sorely missed by me.
Overall, Chaos Faction 2 serves well as a sequel, but I hopelessly cling to hope that a Chaos Faction 3 emerges that fixes any remaining problems.
