I just got the Tommy gun, and i fought that right hand man. its a peice of pie to kill anything. the tommy gun power is level 10, and its infiante, so you dont even have to reload. i just opend fire on the right hand guy for like 20 seconds straight, and he died. i didnt even use those tanks. even the chainsaw guys go down with like 6 shots max. its crazy easy now. now im saving up for the infinate rocket launcher. yeah, i checked, there is a professional mode, ill be doing that one as soon as i beat this 2nd time around. this game is too good to let go
