Conclusion: Zapper is a pretty basic game, with little appeal to hold the attention of hardcore gamers. Which isn't to say the game isn't fun, just probably not enough for most. If you have kids though, or really enjoyed Frogger, then Zapper could be well worth checking out. A decent range of multiplayer modes coupled with unlockables and hidden levels adds some longevity, but it doesn't change the fact that Zapper is one basic cricket.
Pros: easy for young kids, frogger-like addictiveness, fun multiplayer and bonus levels
Cons: controls are iffy, hate jumping? don't get this game, music & sound are very basic
