14 days first try... you just need artillary upgrade, and the weapon upgrades, then it's pie, witht he big guys about 2 feet awat from your base, drop 2 bombs on them. it'll save a lot of time
Strategy for "300"
2 fully upgraded fireman joes on the outside towers, and a "thumper" thing to know the infantry down, fully upgraded. Spend the remaining money on walls, just for fun(you won't get hit) and the rest on a few repairmen.
just because you suck at a game doesn't mean you should rate it low... don't try to kill the town champion until you own a few cities, the champion is an optional fight.
wtf... first 2 levels went fine, then i beat the third... and it said "cheater!" and put me at the menu... when i did nothing wrong... i know right-clicking is cheating, but i never did that.
wow... B-17 took me FOREVER and it still said "excellent"... using a guide would just ruin the game. The who point of the game is to get the feeling of success when you finally stumble upon the solution. If you're not actually going to play the game, go play GTA or something.
