This is the path for the Commander who wants to pummel the enemy into a quick surrender, making a shocking and awesome display of power. Whether it's by speed (jacking up the firing rate), numbers (increasing squad sizes), or weapons (FLAMETHROWERS), you'll be sure to find here a winning way of scaring the chevrons of your enemy. Note at the end the reduced rate Spawn Timer -- your key to spraying the battlefield with fast, overpowered, shell-lobbing soldiers. Mmm -- smell that wartime air ... that odor isn't offensive. It's Offensive.

It has been said, "the best defense is a great defense." Unlocking the Perks in this tree will keep your soldiers on the battlefield longer, making them fiercer and increasing their chance of Promotions. And if you subscribe to the name of the game literally, here you'll find all the Trenches upgrades -- not only beefing them up, but also building them faster with Toolbox-equipped Engineers. For the Commander who likes to keep the good guys alive while the bad guys wonder why their bullets just don't work as well as they used to, the answer is Defense. (Deployable hordes of fans holding pictures of fences will be available in future updates.)

Here you'll find the stuff that bombs are made of. For the Commander that sees this war as an air-to-ground exercise, this Perk tree will bolster your barnstorming biplanes. From the types of bombs (gas, fire, cluster), to their price (cheaper), and from their power (more), to their staying power (lots more), this shopping list has enough bonuses to keep you occupied for some time. And let us not forget the level of support our medics and our bankers bring -- here represented by increased coinage and better healing rates. In the end, your background players on this wartime stage really set the scenery... and then blow it all up.
