Great party game, easy to play, fun for you and your friends. Otherwise shallow and unappealing by yourself.
For $30, this game delivers. Three to four people shooting bad guys on the screen doesn't get old.
Even casual gamers can point a Wiimote at the screen and shoot something - just like a real gun.
The game offers multiple avenues so it will take 3 play-throughs of every mission to "see it all".
Sequences can be failed and you'll continue without restarting.
You can unlock more outfits (which only show up for 1st & 2nd players).
CONS: =======================================
Shallow gameplay.
Enemies disappear after being shot and striking the "you hit me!" pose.
Graphics are okay, but dated. Nothing has been done to spruce it up for the Wii that I can tell, recalling the arcade version.
If you live alone or don't have friends over regularly, buying this game makes you stupid.
============================================
The arcade version of Ghost Squad allows for two players, but the developers went crazy and added four player support for the Wii, even though you'll only see two protagonists during the cut scenes. It's amazingly fun.
Everyone loves to point and shoot at something, and unlike Time Crisis on the PSX (or any other gun game on a console) you don't have to dig out special peripherals to play it - you just grab your Wiimotes and have a blast.
That said, the whole allure is the ridiculously easy gameplay. (Sure, completing the game and accomplishing all of the objectives takes skill, but my 10yo, 8yo and 5yo daughters managed to finish the game almost by themselves; I helped on two boss fights.)
This is a game that makes other people understand why you own a Wii. You throw it in, you pass out the Wiimotes (no nunchucks required) and have a good time.
It is also the kind of game that makes loner hard core gamers hate the Wii's very existence.
There is a limited leveling system built-into the game wherein you gain experience for good shots and the difficulty ramps up; there are also sequences where you use sniper rifles or battle people with knives - most just help break up the action and aren't compelling in and of themselves.
