Thunder Gun on CAMPAIGN
Ok...go to the mission "Numbers" and at the beginning, make 6 NOVA6 gas cannisters explode and the screen shakes. Then go to the back and you should see an office. Go to the little white radio and press y on CCP or A on wiimote+nunchuck on alpha button layout. Then the screen shakes meaning you got the tape. Now...when you jump off the roof into another building, you should find another white box. Insert the tape with y or A and the screen should shake. After a few seconds, the gun appears out of nowhere on the wall in front of you. The first steps need to be done kinda quickly so it may take a few tries so don't GET MAD please.
Thumbs if true and comment. PEACE people!
