I wanted to create this topic to share some tips and advice. Me personally, I don't have many tips but you guys you probably have some. So share them in this topic. I'm probably going to do some more topics like this to share tips.
MY TIPS------------------------------------------ -Always build Barracks because, alone, your tower are not fast enough. -Try to upgrade as fast as you can your Archer Tower and your Bombards. -Build Bombards near Barracks and near the beginning of the level.
i always put 2-3 barrack towers near the end and put archers and stuff near them. as the game continues i put more archers near the beggining to weaken them.
musketeer- great with armored enemies or enemies with lots of health Elven- good for groups of enemies with low health and low armor.
mage (transportation)- the 'attack' version of a mage. Death ray and transport come in handy with enemies with lots of health. mage (golem)- the 'defense' version of a mage. Stone golem is great for stopping big enemies in their tracks.
Paladin- for enemies with loads of health and armor. Buys you time to take them down, or handle other threats. Barbarians- not great with big enemies, but thins crowds of smaller enemies.
Tesla coil- best put at the beginning of a course. Upgrade it so that the lightning jumps through enemies all the way to the end. Big Bertha- possibly the greatest crowd clearer in the game. The missiles are also great for single tough enemies.
I usually use Paladins.They are hard to kill, and all upgrades they become devastation :P I have only few times used barbarians, they die way too easy imo.
If there is some sort of special tower/unit you can use, like the sun burner or Bigfoot, USE IT! it will help a lot.
The sun one doesn't work that well... If you upgrade to all four of em, you might be able to kill 1 unit...
Don't get the sasquatch, its not that powerfull... It's just like the rock thing that you can get from the level 4 mage tower... ONLY GET IT IF YOU ARE DESPERATE!!!!
