the easiest way to get the c-c-c-combo medal is to not increase ramp height at all. you also need to get the ramp re-adjust from the bonus shop and set the ramp to be completely straight. then just get the whirlybird or the chopper and hover close to the ground and destroy everything in your path
lvl 5 isnt impossible... level 9 IS IMPOSSIBLE! i think all of the bomb missions in this game are going to be increadibly difficult. i beat 5 by taking 3 guys down to the bottom/right and taking 2 the other way. you have to be really high ranks to do the level too (my guys were all about lvl 10-13). in lvl 9 u get 2 ppl to kill 5 guys and disable a bomb...
...................WOW. This game is one of the best zombie games on the site. The beautiful graphics, the upgrade system, and the background police/military radio contributes to a fantastic game. This game is so artistically designed and wonderfully created that it deserves to win the game contest 10 times over. The upgrade system is really nicely done with no flaws. This game is even better than 5 star because the background noise is the police chatter. i thought it added tremendous entertaining potential since it is fun to listen to. Overall a tremendous game and i urge you all to rate this 5/5
