YMMV / The Tank Builder

• Demonic Spiders:
  • Large Sniper tanks, which are fought in the later stages. They deal around 250 damage per hit on you on Normal, and 500 per hit on hard.
  • Giant Sniper tanks, only fought in the last few stages. One shot removes about 500 of your health where the maximum you can have is 2840. On hard, they deal 1000 per shot. And they appear in numbers in those stages, and have a lot of health.
• Game-Breaker: The weapon creation system allows for this- in fact, player-created weapons tend to be much cheaper and better than the preset ones. Get a weapon with maximum damage, fire rate, splash radius, and minimal energy cost, then fire away.
• Goddamned Bats: Kamikaze tanks. They appear in huge numbers and rush you very quickly. Hope you have a rapid-fire weapon to take care of the huge hordes...
  • Later on they're replaced with big Kamikaze tanks, which are slower but have lots more health. They still appear in huge numbers too...
