The game is basically "Devil May Cry" + "The Matrix" The fast paced shooting and sword slashing is complimented well by your ability to run up and along walls, dive from and behind cover, and even reload on the go. It's even possible to reload during any of those tricks which makes them great for getting out of a quick jam and quickly getting back into the fight.
Gunz's biggest draw back is how long it takes to get the hang of the literally constant flow of combat. This is by no means your average shooter, this game is only recommended to those with the quickest and sharpest of reflexes.
But to those that fit that category, you'll be happy to learn that Gunz - The Duel scores a 7 out of 10
