How to beat 7 Cities TD for iPhone

Posted: January 8th, 2009 | Author: David Schultz | Filed under: apple, gaming, how to, iphone |

First we had Fieldrunners, then Tap Defense and now 7 Cities TD. The first 6 cities in this game are very easy, but i have spent hours on my train commute trying to beat the last city “Onyx Monolith” and finally beat it tonight with only 7 lives lost. Here are some pointers you can follow to beat this level yourself, and save yourself some frustration (note: i have only tested this strategy on easy):

1) Like my strategy for Tap Defense, it turns out an Arrow Tower strategy in the beginning works wonders. Build them as soon as you have the gold because the more towers standing the more gems you can get with each kill. DO NOT BUILD ANY OTHER TOWER TYPE YET.

2) The mistake i was making was trying to distribute my gem +dmg upgrades across too many towers. I found it best to put 100% of my gem upgrades into the arrow tower in the picture below. Eventually you are just one shotting everything that attempts to pass by.

3) Once you have covered the map in arrow towers and have the gold, replace 3 of them with Obelisk towers, each using different auras (Damage, Range & Speed) and overlapping your “uber” arrow tower pictured above.

4) Continue to spend gems on this arrow tower. You may find a couple heavy armor turtles get by near the end.

5) Once you are comfortable with how things are going feel free to add a few tornado towers before the area where the rivers converge to maximize impact of your uber tower.

6) Use the “Critical Hit” upgrade on your arrow towers as they level up.

Here is what my map looked like when i finished the game:

    Great post! Strategy based on yours (arrow, tons of obelisks, one uber tower, tornadoes with ice devil) works wonders. I was able to get to 130s waves on hard mode on most maps. however, you get overwhelmed by immune enemies eventually, and lightning towers don’t seem to make a difference. We really need discussion forums for this game… I’ve asked developer about this.

    The arrow tower of doom strategy works amazingly well. For endurance levels, I’ve made a modification. Once you hit level 50 or so: In some part of the map where enemies rarely reach, clear out all but one tower, then surround that tower with obelisks. Spend a bunch of gems upgrading damage on that one tower and all the obelisks will increase as well. You’ll soon have an orbital defense satellite one shotting everything… just be sure to sell non-upgraded towers within range of the tower you’re upgrading for obelisk power. In my current game, I have 9 6210 strength obelisks on wave 97 in my current game.

    Totally, Diamond Sky, especially after the update, is too difficult on hard to use the single arrow tower idea. Anyone?

    i haven’t been able to get past diamond sky either, i tried this strategy on easy but after wave 10 lost all my 30 lives in 3 waves. any suggestions?

    …this strategy doesn’t work at all. i tried it on the same level, onyx monolith, on easy. i got up to wave 22 and lost two waves later

    Works perfectly on easy level! I’ve lost 12 lives but surrended :)

    I can’t figure out how to choose different auras with in the same map even when I have all of the skills unlocked. Can anyone help me?

  14. #14 The "G" said at 3:00 am on February 25th, 2009:

    Tap the obelisk of choice. Tap the obelisk icon that comes up, then choose your aura.

    It’s kinda the same step you use to upgrade towers when they highlight.

    In hard difficulty, you have to vary your “Arrow-Tower-of-Doom” a little bit, but ultimately, thats what you are looking for.

    I usually start off by having at least 2 cannon towers.. yes cannon towers.. and spend your inital 2 gems on the 2 cannons. but don’t build more than 4, then add 2/3 more arrows, to make a total of 6-8 towers. place them at a good choke point .

    with 6-8 towers, your gem income will be at a relatively decent pace and not leaking anything. minus the first boss or a few fast/heavy armor.

    then once you hit wave 8/9+ you shud be spending all your gem on your tower of doom, and all your cash to make obelisks, maybe a wind tower or two, but i dont find them necessary.

    I’ve went through all the cities on hard using this method without leaking one single unit

  17. #17 robert said at 4:57 pm on March 4th, 2009:
