Samurai Gunn is a fast paced arena style "Bushido-Brawler." It's extremely easy to pick up and have hours of fun on the couch with your buddies. From the 10 life/kill Death Match to the life or death Shogun Showdown, the battles get intense.
Only having 3 bullets in your chamber makes ranged battle high stakes, but worth calculating. You have the ability to block strikes with your sword, but whoever swings second goes flying in the opposite direction, making battles even more dangerous when traps are activated or when the floors are spiked.
Although the price may seem steep for a local "party-game" this day and age, the single-player survival mode redeems the price. Some may disagree, however the difficulty starts strong and only gets more difficult with each level. It's a challenge not to be over looked.
Overall I'd say Samurai Gunn is an 8/10 and worth a purchase regardless, but it's even more worth a purchase if you have three friends with game pads to decapitate each other. It'd be difficult to implement online capabilities since the controls are heavily based on precise timing, therefore latency would cause issues. This game is exactly where it needs to be, and provides hours of entertainment regardless of couch-buddies.
