It's strange how fresh Wii controls can make the same old game feel.
Control is really where MoH:H2 shines, although they are still not perfect. The Wii remote's IR-sensor is used to point at the area of the screen at which you want to aim. You can set the horizontal and vertical sensitivity, as well as the size of the bounding box that determines how far you have to move the remote off to the side before your character will turn. Turn the settings all the way down and your kids (if you really want your kids playing an intense FPS) or gaming-impared relatives will be able to play the game easier, but experienced players will want to turn the settings almost all the way up for literally pixel perfect accuracy.
So the aiming is great. Movement is handled with the nunchuck. The analog stick moves around the environment, the C button sprints and the Z button does a light melee attack (both oddle during multiplayer only.) Tilting the nunchuck left or right will make the character tilt his body left or right to get a better view when zoomed in. Zooming is accomplished by hitting the A button, while shooting is mapped to B. The D-Pad crouches, reloads, and changes weapons depending on which direction you press, and it all feels pretty good, even though hitting up to reload can stretch your fingers a little. In the single player campaign, the only way to melee is to thrust both the nunchuck and the remote forward. This is spotty at best.
Other motion controls are implemented throughout the campaign, with varied results. When sniping, you must twist the remote left to right to zoom out or in. It's kind of inconvenient at first, but it's not too bad after a bit of practice. Grenade throwing requires that you aim at a certain part of the screen, hit B to lock the destination of the grenade in place, and then make a throwing motion with the remote to release the grenade. That can get slightly annoying because oftentimes the throwing motion will put your remote sensor off the screen, prompting a message telling you to point your remote back at the screen. Other motion controls include: turning the remote left and right to tune radios (fun for about 1 second,) twisting the nunchuck clockwise or counterclockwise to aim a mortar (very fun and cinematic feeling,) and moving the nunchuck in the described fashion while aiming at the screen with the remote to fire turret guns (pretty fun if pinpoint precision isn't neccesary.)
The audio in Medal of Honor: Heroes 2 is not fantastic or moving, but it is good enough to get your heart pumping during an already intense battle. The gunshots and whatnot are really the typical WW2 stuff, which is good enough for MoH.
So the single player campaign is fun and all, but there is actually a ton of extra content in MoH:H2 that makes it better than the sum of its parts. The biggest feature is of course the multiplayer, which supports a whopping 32 players online, but strangely no splitscreen play at all. The online play functions very smoothly for the most part, and with the Wii's precision aiming, there's usually no point in blaming your death on a bad frame rate or shoddy aiming. You'll get a nice selection of weapons in multiplayer, and a decent selection of modes in Deathmatch, Team Deathmatch, and Capture the Flag. I usually stick to Team Deathmatch because I prefer the team based gameplay, and CTF seems to have an odd glitch. It seems that the person who grabs the flag is invincible while holding the flag, which is strange by itself. But the worst part is that the person holding the flag doesn't have to return it to his base; he can just run around and enjoy being invincible. TDeathmatch and even regular Deathmatch are both fantastically addictive and well thought out considering that this is the Wii's first huge online release. Oh, and no friend codes!
Other extras include the Arcade mode, which will be fun for anyone who loves light gun shooters or for those family members who can't get a handle on the story mode. Arcade follows the same story as the story mode, but I found it to be less fun overall because of the fact that you have less control and that reloading in Arcade mode sucks. You have to point the remote off the screen, which basically translates to flailing your arms around for a second or two in order to get the game to recognize the fact that your cursor is no longer on the screen. It's still a fun diversion though. Finally, there are medals that you can earn during the single player portions of the game, which function sort of like achievements on 360 games (only there is no point tally.) It's a pretty fun system, but I can't see anybody really striving to get them all.
Oh, and there's one other small issue that annoyed me. The game came up with a message informing me that my batteries were running low, pausing the game in the process. I didn't have any replacements for the batteries, so I decided to keep playing on those batteries. A message came up about (I'm just estimating) every 5 minutes informing me that I was running out of batteries, and yet I was still playing. This message is really annoying in multiplayer, when it will pause your game every 5 minutes or so and make you cannon fodder for the second it takes you to hit the A button and dismiss the message. I'm not upset about the fact that they warn you of low battery, though. I'm upset about the fact that I've been playing on those "low" batteries for about 2 weeks now, and they still haven't run out. Clearly, they weren't too low.
Overall, MoH:H2 is a great bargain. It comes with a fun but derivative single player campaign, an arcade mode that is surprisingly long, and some very well executed deathmatch style multiplayer, all held aloft by overall great controls. FPS fans, don't miss your chance to see the next evolution of shooter controls, even if the concepts aren't quite up to snuff with the innovative controls.
