Got bored and decided to play GoW3 online on my brothers account.
This is what i've learned from playing 2 matches so far.
They've fixed the Gnasher but If it's Sawed off Vs Gnasher, you'll lose 99% of the time since the Gnasher was fixed while the Sawed off is like "derp You may finally be fixed after three years, BUT THEY INVENTED ME TO BE THE NEW BROKEN WEAPON"
Basically if you ever get the idea of doing Gnasher vs Sawed off, the outcomes will either be you both die by some miracle, you of course die, or the player using it has horrible Blindfiring and somehow misses you as you shoot him in the face.
another two things, Sniper scope is dumb but you can get people behind cover standing still, and Incendiary grenades kill upon impact. (Surprised me when I died to it)
