This is my intake on the best strategy for tower defence. Feel free to leave in the comments on how to improve this. NOTE: This strategy works FAR better on perilous than any other map, simply due to the layout of the tower area. I have an 80% win rate with this strategy, hope you find it useful. First, immediately rush where the mobs will start. The very start of where you can place them on both sides (the first turn) is where you need to work. Put a mage tower on the close side of the start and an artillery tower on the opposite side. Upgrade these as soon as possible. When the other team starts sending zombies, you'll almost instantly get from 15-25 coins per second if you have level 4 towers. Start sending zombies once you have 500-700 coins. Once your zombies have got you to 1,000 coins, place mage towers further down to farm the cave spiders as well. You'll begin to get points crazy fast and you can start to mash mobs. Upgrade your gold to 10/sec first and then buy cave spiders. Cave spiders are going to be your mobs for a LONG time. Snag 500 to get your gold to 15. Then, get 1000 to go straight to magma cube. You may be thinking, magma cube?? Giant isn't that much more expensive! However, magma cubes are much more efficient. Hopefully by now your team has set up point farms for stronger mobs by now and also have magma cubes. Send 1 magma cube as a distraction out into the battlefield. Then, because the other team will be completely distracted, have your team send 4-10 magma cubes out at the same time. If most of them make it, this will do MASSIVE damage to the castle. It wouldn't be bad if you sent creepers first to act as a buffer. You're most likely in Armageddon mode by now. Send in a wave of magma cubes that will leave everyone with 1000 coins. Send help by giving speed boost in the heavy guarded areas and Regen when they're in the open. If most of them get in, the castle will most likely be killed. Some things to note 1. Placing mage towers next to each other is ineffective. 2. Poison towers are useless because of mage towers. 3. Zeus towers are the most effective way to damage giants and magma cubes. 4. Magma cubes are more effective than giants. 5. Don't buy spiders silverfish or endermite. They're just weaker versions of another mob.
