YMMV: Heavy Barrel
- Crowning Music of Awesome: The background music for this game is really good, especially the arcade version (which has never been recorded on youtube or anywhere)
- Game Breaker: Understandably, the game gets much easier once you get the titular weapon. If you're careful, you can save the final piece of the weapon just long enough to vaporize the Final Boss with it.
- Goddamned Bats: Jetpack enemies will circle you to avoid your shots and piss you off.
- Most Wonderful Sound: "HEAVY BARREL!" Which occurs when you get all six parts to the all-powerful titular weapon.
