Double comment, but the vote went to 4/5, because when I destroy a town, I don't always have enough time to get all the money. I have maxed coin grabbing too. :/
Blast it, it isn't "America" it's "United States". There are three Americas, including Central America. Canada is part of America, yet everyone mistakenly refers to the USA as America. This is a minor grumble I have, otherwise, the game is amazingly fun. 5/5
The only reason this game would be hard at all is because of PsychoGoldfish's special move...if you're at the top of the level, it puts you close to death if it doesn't kill you. Damn fish. xD
Okay, with the pearl, he's invincible, don't bother shooting him. Just focus on moving between the lasers so you don't get hit. Also the drone on the bottom is bet killed with guerilla tactics(Shooting then running after a couple of shots) Hope that helped a little.
Ardum, Main Character(Hopefully a mage), and Martine are easily the best combo. I recruited Ryanth, only to get the badge. You need some kind of a tank if you aren't a warrior on your main >.>
To counter the unfair amount of units on the second stage's middle, you need the grenade upgrade. Simply send an Assault Team at the SAME TIME as Rifeman Squad. Have either an Assault Team or .30 Cal Team on each flank. Get your teams close enough to where the enemy starts to shoot, then click the grenade button until at least one gets thrown. You should kill about 10-15 units per grenade if it's packed.
