anybody got any tips for the bunker buster ?

crouch when in battle and pick up and use the AK's rather then your mp5 (bigger bullet better stoping power) try to aim for thier heads to get one shot one kill effect and use the grenades when the enemies are tightly packed together but hold the R or L button for 3 seconds before thowing it so that tthey cant throw it back

um i kno its already been explained but i think its easier 2 understand here well wat u said is correct but eack tick is longer then 1 sec ok just hold down l or r and you will see after a few seconds that the crosshair starts to widen then gets smaller, like a tick it will explode after 5 ticks so let it go at 4 or just a tad after or whenevr u want
