There's not enough money to buy 2 UFOs, unless I sell most or all of the towers. How many did you need? I used three fully upgraded boomerangs, one flashlight, and two partially upgraded gun-things and they're not nearly enough to defeat the boss creep.
should i buy the dlc level.... how many individual levels are in them... and wat makes them so great.
The flashlight is a boss killer. Max it out. When it's at max level it can reach the left side of the map. Good luck
Oh neat I never thought about upgrading the flashlight, since at level one it's ridiculously weak. Should I sell it and place a new one at a better location, or just keep it in the top corner?
I can't remember. Although I did just go back and finish it recently on easy (I think you get more money - not sure about health of the enemies), and on easy I used just the flashlight and boomerangs.
You can't sell it, as it's not an option to rebuild. The key to flashlights is that they do MORE damage as the meter builds up. A maxed out flashlight that never stops hitting a boss kills most bosses. A level 1 flashlight is very weak because it doesn't have the range to keep hitting an enemy to increase its damage dealt.
Ziggurat Here's a walkthrough for hard. Remember to hand target any fast moving creeps. You'll need to sell and rebuy the UFO in the 50s.
You can win without selling. But if you want a higher score it's better to concentrate your power at the end and minimize things like stars and boomerangs
This DOES get you perfect...the gold star! Selling towers doesn't matter in survival mode...only doorbuster and endurance. So why not go for both?
