Although you don't need to purchase the Wii Zapper to enjoy Sega's light gun shooter, Ghost Squad, it and Nintendo's peripheral make a decent combo, considering you can snag both for roughly $50. Just don't expect depth from this terrorist blast-a-thon. Although Sega's arcade port contains extras, you'll play it for a few hours and then toss it onto the pile.

Ghost Squad drops you into the combat boots of the, well...Ghost Squad, a secret group of commandos charged with saving the world from evildoers. Through the game's three acts, you'll explore a log cabin, Air Force One and a jungle, the goal to save people from themselves. It works similar to the Virtua Cop and The House of the Dead games, with you being unable to move and shooting enemies. Along the way, you'll snag bonus items like extra health and up to 25 different weapons, and the game features branching paths, allowing you to choose how the story plays out. One second, you'll wipe out a small band of enemies, and the next, you'll choose between rescuing hostages or disarming a bomb. This alone adds an extra hour to the game, as you'll want to experience everything.

Past that, there's not much to see. Sega did us a service adding extras to the arcade game, but none of them held our interests very long. Unlocking new costumes (bikinis, a panda suit) made us chuckle, and being able to play alongside three buddies ups the firepower, but we called it quits after three hours of wandering through the same environments and blasting similar looking bad guys. The ability to upload scores to online leader boards is a nice touch, but we'd much rather pour our attention into something more competitive, such as Geometry Wars Galaxies.

We're also bummed at the graphics. Ghost Squad arcade isn't beautiful by any means, but it's cleaner and runs a heck of a lot faster than the Wii version, which looks noticeably worse than Sega's 1999 release, The House of the Dead 2 for its dead Dreamcast system. We know that Nintendo didn't model the Wii after Sega's arcade hardware, but we expect higher quality on a current generation machine, and not characters and environments with rough edges.

Then again, and as the saying goes, you get what you pay for. For $30, Ghost Squad offers a few hours of light-gun shooting mayhem, but we can't justify its price. It's an ideal rental and a solid purchase, but only if you have extra store credit. Better yet, and considering it's the holidays, put it on your wish list.
