As you might imagine, there isn't a whole lot of strategy. With the Wii's point-and-click control scheme, you can easily dispatch each unit type to attack whatever it will hurt most, but it's usually better and equally viable to tell everyone to just attack the same target. After all, with gunship choppers and artillery, you pretty much have your bases covered. Everything else is gravy, although only infantry can capture flags.
New in Battalion Wars 2 (but not new to the Advance Wars series) are naval units, which for the most part behave like tanks on the water. You have your standard battleship (essentially floating artillery), frigates (which kill air units and submarines), and submarines (only visible to frigates and subs), as well as dreadnoughts (better battleships) and transports (for transporting). The submarines can dive, which makes them invisible to battleships, but can then be spotted by frigates or other subs. Tactically, the sub's advantage is negated by any fleet with subs or frigates--in other words, every country's navy.
Although the same "Everyone shoots everything" strategy applies to the new naval battles, Battalion Wars 2 is superior to its predecessor in one important regard: The campaign is much more entertaining, due to its pace, structure, and difficulty. Instead of throwing you into one giant, overwhelming battle after another, most missions are broken into more manageable pieces. There are usually several small skirmishes leading up to one larger confrontation, with side missions and the occasional surprise. The overall game is easier, but given that there isn't a whole lot of room for skill, it's also less frustrating. We know "pacing" isn't the most exciting word, but between Battalion Wars 1 and 2, it's the difference between fun and boredom. This is essentially the same game as its predecessor, but because it feeds you action more thoughtfully, you'll happily play all the way through the six campaigns.
Once you finish there, you can go online and play either cooperatively or against friends and strangers. In the handful of cooperative missions, you and your comrade each have armies, with the important units divided between each. For instance, if you have antiair infantry, your partner will have antitank. As a result, you must watch one another's backs and work together. If you aren't feeling cooperative, you can take on a human opponent in assault or skirmish matches. Assault mimics a typical level, with one player attempting to complete a series of objectives before attacking a base, while the other defends, and then vice versa. On the other hand, skirmishes are simply deathmatches where you and your opponent kill one another until the time runs out. Whoever does the most damage wins.
The good news is that all of these games are easy to get into and were lag-free in our testing. The bad news is that you can't customize anything. Each map type has a handful of preset levels with preset unit loadouts, and services only two players at a time. Battalion Wars 2's online content is a good addition, but more options would make it better.
On the other hand, the presentation values are excellent. This game looks much, much better than its predecessor. The graphics are crisp and clear, the water looks wet, and the action unfolds without a hitch. Furthermore, the audio themes are so good you'll actually remember them after you stop playing, and the voice work is absolutely top notch.
Even though most of the original game's shortcomings are still present in Battalion Wars 2, this is a much better product thanks to improved graphics, good pacing, and a decent attempt at online play. Though it still doesn't match Advance Wars in terms of brains or brawn, this Wii soldier is worth sending into battle.
