new weapons : hammer (maybe only brutes can wield it) , dual sabers , a new brute rifle , a brute nade and a mobile plasma turret ( which i also think that only brutes can wield). enjoy^^
The last time I played halo 2, was maybe a month after it came out, and if i recall correctly, the plasma sword was an instant kill no matter the circumstances, why in hell would you need two of them.
