Ok, just reading the new 360 mag, with n ew Quake 4 pics and interviews with id dev Tim Wilits...
Anyways...
The Blaster and machinegun both carry a flashlight. You all know this.
But did you know that the Blaster and machinegun can be Dual-Welded...
"The Blaster and Machinegun both have flashlights fixed under the barrel, and used in tandum with a secondary weapo, say, a railgun, will offer a threefold advantage."
Erm...?
Ok, upgrades.
Weapon upgrades are given by the techies you meet in the game. And the lightning gun doesn't just hit one person, it jumps from enemy to enemy...
Duel wielding in Halo was crap, one thing I've always liked about id is they've never arsed about with secondard fire functions and silly messing about with weapons.
