Strategy

 * Note: This strategy section mainly focuses on the BTD5 and BTD6 iterations of Round 43.

Round 43 introduces many more Ceramics in this round. Strategies that barely pass the BTD6 Round 40 MOAB with a meagre amount of regular bloon defense or the BTD5 Round 40 Ceramics and Rainbows will likely struggle heavily on this round.

Tips

 * Adding a Glue Gunner with Corrosive Glue is a good idea to add for this round, which both slows down affected bloons and chips away at their layers.
 * If relying upon Spike Factory defenses, Spiked Balls is a good support to add. It will deal a good chunk of damage to any tanked Rainbows and Ceramics. Similarly applies to Spiked Ball Factory, although a somewhat less reliable.
 * Defenses that rely on weaker Snipers on Strong to reduce stronger bloons may struggle quite a bit on this round. For those types of defenses, suggest upgrading them to any Tier 3+ upgrade, each with their different uses, or at least add Point Five Oh/Large Calibre to make them a little more useful on this round.
 * On Bloonarius Prime, Round 43 is difficult due to this round moving along the alternate lane.
