Hm, I've never used this new Auto-Update feature. Maybe, because I build only a few turrets at the beginning and do a full update, I should try to build more turrets with less updates, maybe a better way for multi-path maps. :lol:
Another hints to survive till Level 60
-avoid multi-Path maps
-play maps with alot "U-turns" (mostly all of MY maps
)
-spend every free Dollar in Colonies and update them first, then buy new ones. If you make enough money with Colonies (at least 1000 each round), spend the money and buy Depots. Keep the money under 3000 or so, so the Depots stay at $280. Wait for a fat enemy, then sell ALL Colonies, have at least $6000 or more Money left and at least 25 depots, after killing the Enemy, the depots make the money explode after a few waves.
Before the enemy dies, you still can buy Depots for $280, the price rises only after the enemy has died. Don't buy Depots after the money-explosion.
With only Depots, you should keep the money over 10000 and more each wave, never buy more Towers than you need. better loose some lives, they are cheap and can buyed later when you have more money.
This tactic may not work on maps with small building space.
