While yes, the endless waves of overpowered bosses do get slightly repetitive after a while, I can't deny that this was one of the most eye opening gaming experiences I've had.
Before this, I played the original 8bit game before, and had the irrational expectations that most of the games in this genre would simply be the same as that one. Fun and easy, like the digital translation of a snack. But NO, this is much more than that. When we opened to a van smashing through a crowd of robots in the middle of an apocalyptic city, my mind was blown. Seeing the advanced 16bit technology being used to enhance the game experience is amazing, and very few times did I feel like the game was half-hearted. I haven't gotten past the Constellations Boss, but I already know that this is my favourite 16bit game. Even better, my favourite game on the entire Sega Mega Drive.
As for the story, it's excellent. An epic story sprinkled with some cheesy Rambo elements, and you've got Hard Corps.
Get your hand on this game, it's well worth it.
