I really hope that the supermutants are still stupid. I recall from the first time hearing one, that it was very large, very angry, and very stupid. I litteraly laugh when I am fighting and killing them. These new supermutants look smarter, but hopefully they are still stupid muscular pinheads with big guns.
They remind me of Brutes from halo. They act the same way, and are fun to kill.
"STUPID HUMAN! I WILL EAT YOUR BONES!" -Halo brute
"DIE PUNY HUMAN! I WILL WEAR YOUR BONES AROUND MY NECK!" - Fallout SuperMutant brute.
Coincidence? I think not!
