Heh. Really? Almost the same...?
And yes, turrets beat soldiers 'cause you can't kill a turret and turrets tend to have way better range...and they can even combo with soldiers if needed =D Cavemen are just as meatshields so the turrets can do their thing. Also, 2nd/3rd age turrets fail for their cost -_-
Random notes on cost ratios (enemy units give cash equal to cost*1.3). In other words, how many cavemen you can send out against one of these and still break even (though turrets will usually finish them before you use this many). I might be off by half a caveman or so, but I haven't played in a while, so I forget enemy values.
Caveman vs:
Caveman: 1.666 cavemen
Slingshot: 2.5 cavemen
Dino Rider: 8.666 cavemen (that's insane...)
Swordsman: 4.333 cavemen
Archer: 6.333 cavemen
Knight: 43.333 cavemen (lolwut?)
Duelist: 17.333 cavemen
Musketeer: 34.666 cavemen
Cannoneer: 86.666 cavemen (geez, talk about overkill...)
Advance here, as cavemen cannot hold off melee infantry, period. They get one-shot, and you can't hire them fast enough. Send out a few melee infantry to keep the enemy infantry away, but build a Double Turret as soon as you get $14,000 and watch the carnage. Replace the eggomatic each time you get $14,000. I don't know whether you need troops on Impossible, but they're unneccesary on Harder. AFAIK, in Harder, enemies have 75% more HP, and on Impossible, they have 325% more...or so I heard.
Advance to 5th age when you get 150,000 EXP. Replace double turrets with Ion Cannons as you reach $100,000. Now I'm not sure if four Ions can handle enemies easily on Impossible, but no troops are needed on Harder...so if troops aren't needed, sit back, wait until you get a ton of money, then spam super soldiers. In some cases, the Ions might actually kill the base if you wait long enough -_-
Can someone clarify Impossible for me? Namely:
-Is +325% HP roughly the right amount?
-Are troops needed in the 4th and 5th ages once the turrets are up?
