- Good Bad Bugs: In addition to the enforcer bug and the Mikey bug, there's also a tank bug. On tank levels, if the number of bouncing cannonballs reaches 20 at the same time, the tanks will stop shooting. If you can avoid the existing cannonballs until they disappear, the level becomes easy.
- Luck-Based Mission: The placement of Hulks, Brains, and human family members is completely randomized at the start of each wave and each life. This means that, while one turn can result in scoring thousands of points and several lives, the next might result in few points and several quick deaths.
- Most Wonderful Sound: The good old bleeps and blips!
