Vanquish was made by an incredibly famous Japanese game designer: Shinji Mikami. The dude is responsible for the Resident Evil series and the Devil May Cry series (among others). Moreover, Vanquish is coming out of the newly formed Platinum Games studio that just released Bayonetta earlier this year. The studio is made up of former Clover studios folks (Okami, Viewtiful Joe, God Hand, etc.) along with other Japanese game design luminaries like Mikami.
These Platinum Games guys are modern day legends.
Anyhow, Vanquish is nothing like Halo. It's much more of a frenetic version of a Western-style cover shooter like Gears of War, mixed with elements of Japanese action games like Devil May Cry, God Hand, and Bayonetta. Definitely not for everyone. But very much for fans of Japanese action games (and of games in general).
