It might be that you actually have to kill 10 robots when the chain goes off?finndo77, thanks. I set it up exactly like you said and I still didn't get achievement. But I set it up like that with 22 mines and I got it, lol.

How does scoring work anyway?
Only on Lvl34 or something and averaging 700,000 - 1.1m per level.
No matter what my lives left, money etc is, I always get roughly the same and never end up with much more than 500,000 points before everything is added up.
Did at one point have a bonus of 172 during the game, exited the game and continued 1 minute later and my bonus dropped to 66! Why?
Hate jeeps. Some of them are so fast that nothing touches them, especially in the early levels where your weapons just don't seem to be killing anything.
Same with helicoptors. Generally lose up to 3 lives as soon as they appear around level X-15 as I can't get enough to build AA defenses in time and if I do, one missile launcher generally isn't enough (tried the guns and wasn't aware of them even firing!)
Have occasional games though where there is no aircraft activity until a third or so into the game which gives me a bettr chance to increase my defenses.
Not sure why the upgrades say things like "increase starting cash by $90" when I've no idea what the starting cash actually was. Would be nicer if it just said "starting cash $120" or whatever.
Those turrets seem to kill nothing for me. Even in the first 5 stages of level 50, I can have the most basic men just strolling through everything without being touched.
Find the killing of jeeps a bit inconsistent.
Had a few waves yesterday or say 20. First wave passes through everything I have without a single kill and that's with slow towers, and forcing them around corners etc. Then the next wave moving at the same speed and the same number of jeeps gets totally decimated before they get half way across the map.
Do think AA missiles are too expensive. $20 for a rocket tower, then

...
I drew up my basic map layout in the attachment (RDbasic.jpg), hope you can see it. R=rocket; S=slow; G=gun; A=antiair rockets; T=teleport; M=mine. All are fully upgraded except Gs which are just acting as maze walls. The ones with a full-stop after the letter aren't really necessary and I usually save the money. One tip - if Wave 100 has little air troops, then sell off all your As for extra reward. If there's air then just try to sell what you can without losing perfect health. Another tip - set up two Ts before Wave 15 and put a S before the first T so you have more time to recharge the T.
Why this map works for me: (1) overlapping fields of R fire gets most of the land troops; and (2) the A fire gets the air except for really bad air waves where you need to micro the T. If any air gets true then keep recharging your Ts and hope you stop them all. Have some extra Rs near the end to upgrade to As if you think the air wave is too strong.
I've tried different setups using upgraded guns, artillery, flame etc but none of them worked as well.
I would be happy to hear any suggestions on how to improve this. Thanks.
I'm on level79 at present and they just keep walking straight through everything I have. The amount of times a slow moving man strolls through a whole load of rockets, slow towers and guns in the first few levels is amazing!
I've been trying various techniques mentioned here but just can't win.
On Level 80 now and the amount of times I lose 20-30 lives in the first 34 stages is amazing! They just stroll through everything. Even tried going back to say Level 50 and getting more money from that but when a rocket upgrade costs $1.98m and I'm getting less than that after losing one life due to some jeep being immortal, it's not helping. Would be useful if the $$$ carried across as well as I'm losing loads from not being able to afford anything other than "flame tower duration" and I never use these.
Consistency would be good.
Sometimes I get one slow moving helicopter that goes straight across all my air defenses and slow towers and makes it through without a scratch.
Next time there are 3-4 helicoptors and they're wiped out in seconds with the same weapons.
I've had 20 maxed out air missiles before and still had 8 out of ??? jets getting through to the other side.
Just had one game on Level 51 where 3 jeeps, that if they were any slower would have been stationary, casually strolled through around 40 defensive turrets including ones I was frantically building to try and stop them and divert them closer to rockets.

I call BS. There is just no way you have read all seven pages and still have problems! How about you read them again....sloooowly![]()
I did scrape through level80 just now with 8 lives left and got $1.8m for it which wasn't enough to upgrade my rocket power or cash at the start.

Think my major problem is that I orignally bought the mine tower rather than the teleport tower.
Added: Got the teleport tower now. Shame it can't be placed anywhere other than on the route for aircraft or am I missing something? Did want it for jeeps but they will just drive around it.
Met the Titan too on 90-87 or something like that. Had full health and he didn't last that long.
Any way of stopping my Desire turning off? After a couple of minutes of letting the game run on FF without touching the phone, it dims the screen and shortly afterwards goes into standby.
Most other games prevent this.
Xenole, what levels are your weapons at? Level 80 should be easily winnable with level 5 or so on everything.
And I guess I have a different idea of what a fun challenge is on this game. I am currently at level 14 on all my weapons. I've unlocked all the little extras that came in the latest update. I think I'll clear the level 290 game that I'm currently playing, but it will take a while to find out. I never get to fast forward, and the screen requires my constant attention. I'm looking for the "wall." How far will I be able to progress through the game without upgrading weapon base levels any farther?
