The original Gears Of War had a narrow selection of guns available for the player but it was one of the best console games ever made; and if the game's lead developer is to be trusted, don't expect a different formula for its sequel.
In a recent interview, Cliff Bleszinksi, lead developer of Gears Of War and Its sequel, was asked about weapons customization in Gears Of War 2 and clearly ruled it out. "We're not really that kind of game. We're not going to allow you to bling out your gun. The Lancer's a Lancer, Gus is Gus, and Marcus is Marcus. Those are the identities we're sticking with", he explained.
Bleszinksi's then went on to convey how much he loves GoW 2. "Just the other day I was driving in this icy level with a tank and power-sliding through Locusts and Gus goes, 'Locust roadkill, baby. Squish. Squish. Squash. Squash.' It was just freakin' great. And then when you shoot you're knocking over trees because we have more destroyable objects and you shoot your Boomshot and everything shatters apart."
"Gears was heavy and Gears was chunky and Gears felt satisfying. And Gears 2 is just really taking that to the next level. It's just cooler and more visceral."
