I'm gonna get some flak here . . .
But I didn't think this one was as good as the other two Combat Instincts. I think you're leaning more towards style and away from actual substance (a la DBZ). I'll just kinda break down my quips with it:
Graphics: The graphics are the best I've ever seen in a Flash game/movie, period. But, there are only 2 problems I see, one of them being minor which is the overuse of effects like lensflare which look like explosions and can be ultimately distracting and a major one, which will effect . . .
Gameplay: The gameplay here isn't too much different from the first two, except I don't know about you guys, but this ran very very slow, even on Low Quality. This made the game almost unplayable because my machine simply wouldn't respond promptly.
Story: The whole opening thing seemed kinda corny. It's like you turned your allies in the second one into enemies just for a plotline for the third one. But that's not my bitch about it, that would be a good idea, but the execution of the opening story came out fairly corny. It was almost as if the dialogue was written by a 12-year old in Counter-Strike and then thrown through a translater to fill in the rest of the words. This became a problem in the second one, especially during key sequences like when you had to take out those snipers on that hill "HAHAHAHA, Headshot!". I don't think trained alien soldiers would be saying that. But overall, the story felt a little cheaper than the first two.
Overall: Great graphical effort, but I think you should focus more on elaborating on the story more, because the Combat Instinct series has always been a good story backed up by good graphics, not a sorta ok story made up for by excellent graphics.
Let the flaming begin.
