Changes

A new flying threat is introduced in this tier under the name [[KoboltKobolts]]. They will aggro your defences and suicide with an explosion on them if they are close to their paths. In the event your towers survive the impact they'll be stunned for the next 20-30 seconds. All previous special enemies make their appearance as well in this tier. At wave 5 there is usually a special surprise, the [[Zapper]], a boss type enemy with the abilities of a [[Kobolt]].
