Could someone help me to beat adventure mode. I'm trying to get Skelzor,Genghis Khan, Marco Polo and Drake. My boosters are regenerate and team safety and cluster bomb as kickback.
I think you can complete all the other co-op on crushing except airport, because lots of lives are wasted when the RPG's come. Here's the trick which I used :-
When that scene comes, just go as behind as you can and wait for the chokers to come. Then Kill the chokers. After some time no choker will come and that means all the chokers are dead. Then Pick up a sniper, kill those armored RPG's and go ahead. If you can get a party of 3 skilled players, its better as you can tell them to stay behind.
Heres a tip.
If you are doing it to get the star, keep quitting and rejoining games until you find a skilled group. Also you can join a map at the end and still get completion credits for it.
Explains where they all are.
