Just an idea, but how about having 1 or more electrical traps. ik you guys said your mostly done, but i think a really good t3, or t2 electrical trap would be a high voltage tesla coil. that functions like an area denial system. if something walks in range it strikes them with a lightning bolt, and rebuild charge to strike again, the bolt could do significant single shot damage, and also stun or even knock zombies down, perhaps even make them smoke/smoulder a bit from the direct strike for a while after. upside is it would need a bunch of fancy animations, the electrical attack animation already exist. the tower itself would be a simple 2 or 3 block tall design. it would be an easy, but excellent choice of a new electrical trap. As for the second idea. How about a punji plate/wall it would look similar to a dart trap, but would instead shoot out 5 or 6 spears. stabbing targets 1 to 2 blocks in front or above it. also easy, and unique.
