It may be a bit buggy, but Red Steel succeeds at being a good FPS for the Wii. It's not perfect, but not terrible.
The weapon use in this game is ok. The guns are used the best. You can only hold two, but that is enough because it is pretty easy to kill people. The grenades are okay. It can be difficult to throw grenades but you'll get the hang of it after you fo it a lot. The last is the sword. Like I said before, this game didn't need the sword, but I enjoy it. It becomes a major pain at times because you can mess it up a lot and that can lead to multiple strikes from the enemy. I think parrying is a bit more simpler and easy to do and a great way to counter their strikes and feed them some of their medecine. Weapons are good in Red Steel, but I think they could have done better.
The use of the Wiimote and Nunchuck is great. It feels liek you are really fighting. Whether you are shooting a gun or swinging a sword; it just feels real. When you want to shoot, hold the gun like you would in real life and shoot using the B button. When you want to swing your sword, just take a big swing and you either hit him or his sword. When you want to pick up a gun, flick down with the Nunchuck and pick up a gun and start shooting for your life. I think it is used pretty dang well. There is no doubt you will find glitches or bugs. I once was stuck inside of a support beam that I later found out was too small for Scott to even fit in. It will indeed be SUPER annoying, but you learn to live with it.
Overall, this game is a competent game, but could use a lot of improvement. I would give it a shot if you are an FPS fan, but want some sword fighting sequences thrown in. That is being a bit specific, but still.
