Essentially, Metal Slug 7 is one for the fans, designed with an "if it ain't broke don't fix it" mentality. There's nothing here that revolutionises the series, indeed there's nothing here that looks remotely modern. Some might even say it's a step back, given the disappointing lack of a co-op mode (a long-running series feature), and no online leaderboards means there's little replay value. Still, Metal Slug 7 provides its army of die-hard fans with seven new levels to battle through and new slugs to enjoy. It might be too hard for most, but it's just about right for those who care.
