Wired's Chris Kohler got some hands-on time with Ghost Squad:
"A couple Japan trips ago, four of us had a grand old time playing Sega's massive four-player military light gun game Ghost Squad. I'm pretty sure it was Ghost Squad. We'd been drinking. At any rate, Sega is definitely bringing Ghost Squad to Wii as a two-player game, and strangely enough I had a great time playing it even with the freakin' Wii Zapper."
"With all the Wii Zapper content coming this year, 2007 is the year of Wii shooters. Ghost Squad seems like it's going to give Umbrella Chronicles a real run for its money."
