Takumashii: What strategy did you use after the first two levels? I was doing well on the hard one before farming, but then everything just fell apart.
The awards Elemental Focus and Elemental Mastery don't appear to work. I tried making all my units a single element, and I tried making one unit of each element, and neither award unlocked.
Anybody know how to unlock all the hidden units?
Plasma Tower: Destroy 5 enemy Corona Towers.
Carrier: Destroy 1 enemy Carrier.
I don't know how to get the Secret Striker or the EMP tower.
Oh, I see that you've put the spacebar instruction in the inventory as well. The problem is, if you exit the inventory with an item, you can't open your bag again, so you can't get into it to see the message.
I skipped the tutorial and got stuck with an item on my pointer. I only figured out space when I checked the comments. You should add that to the game description, or make clicking on the lower bar put an item away (maybe both)
Juken: To beat level 18 you have to use your titan unit, or angels if you have them. They'll damage him without getting into his attack range, and eventually you'll take him down.
Put your arrows on autofire and upgrade your energy as much as you can. If an enemy gets past, use a dwarf or two. Upgrade your tower to level 3 when you hit 1500-3000 energy, and upgrade to 4 at around 5000. Once you hit max energy, spam maxxed wizards to win. On the later levels you'll need to make a titan unit as well, 15 wizards then a titan, and repeat until you win.
