I rented this game a LONG time ago. Such a overlooked gem, it was actually made by Treasure, the folks behind Gunstar Heroes and Sin and Punishment.
It really wasn’t anything like Treasure has done before. It was more beat-em-up than shoot everything.
I really liked the combat of the game. Reminded me a bit of Double Dragon meets Smash Bros. I suppose. There was a lot of useless stuff to find and collect in the game.
If you ever find yourself an old copy, give it a try. I doubt you will regret it.
