mod attack earth

1(pardon for my english).i have a simple mod idea.for example,look the big aliens ship of the tráiler.put this ships (the more bigs),in some point of maps of gta.now the 1 ship launch over city a nuclear ray in 30 second(ray type independers day movie))(big explosión under the ship(in ground))(you star for example under this ship(in ground),and have to rescue a people in point two,free,four;(this point under the ship tree,for,five),you have a limit time for can rescue this people o the ship (3,4,5),o launch the nuclear attack the ship 3,4,5(they make damage in a  determinate distance of map) in this área and dead.you can get a cars,motorbike,ectrr,for go to next point and save this people.for more action can put zombies in some sites,(only walking in this place).

posdate:can put in your mod of hulk,for example no only 1 hulk enemy?,for example two enemies at once ?(o more best,a enemy hulk,and other (termineitor,robocop,ectrr,but each with their strongest attacks)(i think more destruction and action).yours  mods are fantastic.please more type superheros  attack and magic........uhhhh...neo of matrix ?,nice chars for this game,and much mister Anderson for enemy(all have big attack).this are very good too.
