Meh.
Not a fan. Gears is an over-rated franchise. Note the constant downward slide on most-played games list. They need to do some serious rethinking of netcode and multiplayer ideas in order to regain their momentum. Cliff and company really shot themselves in the foot with Gears 2 by under-delivering in almost every way. Lots of people are doing gears-style combat in comparable fashions, and in some cases better. Those mechanics are getting stale fast as everyone and their uncle borrows the 3PS cover and shoot formula.
