Ok, let me rephrase my comment.
We NEED Badges!
An easy one could be like, getting a cerain amount of multiplier
A medium one could be killing a certain God like Baal
A hard one could include killing all the special fights and like getting 20 shadow clones kills or something
deniska: I'd like to point out that you're wrong. There are so many strategies for choosing towers. When I first started out, I used to think that high level AOE temples were the bomb. Then when I found out the the crypt's missiles home, I thought those were definitely the best. But as I played on, I soon found out that the crit den are the best towers in the game. Almost every time, I would put a crit den on a high land. Why? Coz a high level crit den can take out ninjas in 1 hit (before they even go stealth). Besides that, they rock at taking out creeps that are almost at your jewels coz their damage is almost instant.
day 75 HC!! woohoo!! 5 days more before I dominate the RNG
But seriously, for all of you out there searching for the golden strategy, economy is the way to go. Not gravity guns, not rapid bowguns.
My museum generates 600 gold per day and for 1AP (chickens) I get a bonus 4k/day
Little sisters are sick by the way, they're rocking somewhere near 1.5k damage. Catch a boss unguarded and *boom!* instant death
thundrbird147, the game doesn't get insanely hard. You just need to be wise at the start and invest and of course, use the correct weapons. I have a day 150++ hunter and right now i'm on day 55 hardcore.
