Bone Busters Inc. is definitely underrated. It's a simple game covered in an almost nostalgic skin due to its highly ripped off theme. A Ghostbusters pin would have been far more lucrative and long-lasting, no doubt. Bone Busters Inc. comes close.
What makes it good? It's simple. Lock up to three of your Bone Busting crew, then let them loose on the town zapping up skeletons! Locking the balls is one of the easiest things in the game, too. Gottlieb definitely wanted the novice players to keep inserting quarters. Shoot the left ramp (Maxwell Street) to light a randomly-lit lock. It's either going to be the ramp you just shot (Maxwell Street), the lower left capture (Headquarters), or the lower right capture (Moon Street). If the randomly chosen lock isn't Maxwell Street, the ball launches into the right ramp area so you can use the second flipper button to control a diverter (mini-flipper) to send the ball over to Headquarters or down to Moon Street to lock the ball. It's relatively easy to figure out. To start multi-ball, launch the ball up the center jump and over the bridge.
There are a few other noteworthy things that happen in Bone Busters. The upper left flipper can send the cars over the highway to collect the lit value on the right. The value is increased by hitting a target or completing the drop targets. Once dropped, the lit car value is also awarded over the highway. The lit value of the car being served is changed by hitting various targets on the playfield which make it difficult enough to choose the one you want.
Also of note is the extra time earned after your game is over. When lit on the outlanes, the ball adds bonus time that is granted after your last ball has been used. I've had it as high as 40 seconds where multiple balls were available for that time to do with as I pleased. I couldn't earn locks or increase any values on the table, but I could score what was there. The manual doesn't explain this so it's a bit confusing as to why it's part of the game at all.
The bottom of the playfield isn't normal either. The inlanes are curved, meaning that fed by the highway shot keeps the ball flowing much more quickly. There are no slingshots near the flippers either, but kick targets to keep you thinking. The ball just doesn't move around this area of the playfield as you expect it should. Things like this keep me intrigued.
Also of note is the Opera Jackpot which increases game to game if not won. It can get very lucrative to light it and collect by hitting the captive ball on the left. Nifty feature to keep people playing.
The skull topper laughs and taunts you with really bad one-liners. "Did you hear the one about the traveling salesman?" repeats over and over. "This eye's for you babe," is because he's a one-eyed skull. He's amusing in attract mode, but repeating every ten seconds on the slowest setting is just too frequent.
Being System 80b, the high score is the only one kept on a power off. There are two buttons on the front of the hot pink cabinet for initial entering, something I'm sure Gottlieb made intentional. If you put in your initials so easily, why not keep playing to do it more!
Overall, the game is quite easy to play but hard to master. The bright pink cabinet and the skull topper are fantastic aesthetics to a quirky game. I'm glad I picked this one up and am having a great time playing it. May not be for the more advanced player, but casual players can feel like they've achieved a lot in a two minute game.
