As someone who enjoyed shooters at the time this game released, I liked it. The gun building system wasn't anything groundbreaking, but I thought it was fun and allowed you to try different play styles. Story is a bit out there and was never considered canon (till recently with the remakes) but I'd be damned if I did play a game attached to the FF7 universe. Takes place after Advent children if I remember correctly.

Tips: keep moving, keep shooting, enjoy it for what it is.
