This is a game that takes two popular video game genres and attempts to merge them into one.
Essentially what we have here is a hybrid between a third-person shooter, and a simplified real-time strategy (RTS) game. As the commander of your small brigade, you have control of a single unit at any given time, using a third-person perspective control system. This is unlike a conventional RTS game, where you play from an overlooking god-like perspective. However, you aren't committed to using this unit throughout the mission. At any time you are able to switch control to another specialist unit, whether it be your standard infantry, flame veterans, bazooka veterans, or even your vehicles.
Simply playing as your units isn't enough though. As you play the missions you will find that certain units are much more effective against enemies than others. While you're using your bazooka to take down an enemy tank, you have to think about taking down the enemy transport helicopters that are coming in to supply back-up.
Thankfully, this is where the ability to command the rest of your units comes in to play. Instead of letting them think for themselves, and subsequently get themselves killed because they have no idea what kind of gun they are holding and which end they should point at the bad guy, you can set them commands and hopefully lead your men to victory. Using the D-Pad you are able to select all, or each individual squadron of a specific unit to attack, wait, or follow you.
Using these commands, and a little multitasking ability, you can direct your anti-air guns to attack the enemy helicopters while you send your flame veterans to defend the anti-air tank from the enemy bazookas. At the same time using a bazooka yourself to blow up the enemy tanks that are trying to kill the infantry you have sent to capture the enemy's base. When you first begin, it can be a little confusing and hectic, but after about fifteen minutes of play the battles will end in your favour.
Controls are pretty basic, which is good, because most of your attention will be focused on commanding your units. The Nunchuk's analogue stick moves your unit, the Wii remote is used to aim. Pressing 'Z' locks the camera view to an enemy, but you still have to aim at it to kill it. Other movements, such as jumping and roll dodging, are assigned to the Nunchuk's waggle and respond quite well. When you take control of an aerial unit, the tilt of the Wii remote comes into play. Diving allows you to avoid lock-on from enemy anti-air units, barrel rolls can be achieved by tilting the Nunchuk, and shaking it while in a submarine allows you to dive. Everything works smoothly and responsively. Unfortunately Battalion Wars 2 doesn't really step up the action enough for good controls to make a lasting impression.
As far as the multiplayer goes, there is no option for a local offline battle. All multiplayer is played via the Nintendo WiFi connection. There are a few modes to play, ranging from the standard co-operative mode, where you and your friend work together to take objectives from the computer enemy. Some kind of voice communications would be nice here, but since there is no such thing on the Wii as of yet, you will have to settle for preset list of text commands via the Wii remote. If you would rather fight against each other, there is an assault mode, which gives one player objectives to take while the other defends them. There is also a standard battle mode, where the objective is plain and simple - kill all of your opponents units.
As you progress through the campaign, more and more versatile and specialists units will appear for you to use and fight. Not only do more specialist ground units appear, but you are also given control of air units and naval units. The theory of the game still stays the same though. Tell the unit that has an advantage over the enemy unit to attack, while you sit back and make sure everyone else is doing their job right. The game doesn't get much more complex than that, which means, once you've played it through once, you probably wont find yourself bothering to play through it again.
The campaign is also rather short. Most gamers should find themselves completing it within a few days of playing; that is, if it keeps your interest long enough to keep you playing for more than one mission at a time. As each mission feels virtually the same as the last, albeit with a few different objectives, you can find yourself quickly becoming bored and losing the will to continue playing. If you are the type who loves real-time strategy games, this will probably feel too simple. And even though it is technically a third-person shooter also, it really doesn't involve the player enough to capture the attention of a player who likes that genre either.
Combining the two strong genres has crippled Battalion Wars 2. Overall, it probably would have done a lot better focusing on one of the genres and making things a bit more complex.
Essentially, Battalion Wars 2 is a simple and short game. It doesn't offer any real replay value, and the story is far from captivating. There aren't any major flaws that make it unbearable to play, it's just there also isn't really anything outstanding, leaving a rather average game. If you do find yourself enjoying it enough to play more than 30 minutes at a time, the multiplayer in Battalion Wars 2 may make it worthwhile. Otherwise I'd say that this is a game best left to a weekend rental.
