Maybe every ten waves, the world gimmick changes having certain special tiles, barriers, heat, plant/zombie drops, etc. The exceptions to this are Motherboard Mayhem, Memory lane, and glitch sitch because zombies from the first can use powers at all times (but are very rare), all types of zombies from the second can appear, and glitch zombies still create darkness.
