My first and last wish as a Gamer

I am an avid gamer, and my first and last wish is to turn this rough idea into a complete story, and then into an FPS. As you may have noticed, i am weak in grammar, I lack expression, and English is my second language, but still i believe what i presented
here is something new and original and could make a killer FPS.

I lack the talent to write a full story including missions, please i request all those who read this to take this rough idea and turn it into a full fledged Game. Any input into this story is welcomed. I also request the mods, writers and developers to see
its potential or tell me whether it's a cliched story.

BUT PLZZ GAMERS HELP ME TURN THIS INTO A FPS...

If the mods, developers , and writers do feel it's something worth developing on, then i give you the full rights to take this dismal crude and turn it into something complete and wonderful.

In the vast stretches of Mongolia, an advanced race was found terraforming, to transfer its fauna to Earth. The local military was sent to explore the area but none of them returned. As things go deeper, it was found that a cataclysmic war has wiped out
the natural habitat of that planet, and some passionate scientists and nature-lovers has teamed up with the remaining army to save the planet's fauna. Their more larger plan is to completely terraform Earth to make a sustainable environment for their planet's
animals. You start in the vast desert in Mongolia and slowly traverse around the world's desert to fight these creatures and discover the source from where these creatures are spawning.Slowly you find the mothership from where they are being transported, and
destroy it.

The sequel

When you entered the mothership, you encountered mechanized soldiers who were trying to stop you, just when you thought you had their boss, he escaped through a portal. You later discover his real intent is to use Earth as a base of operations to stage a
counterattack at the race who tried to overpower them. In a sudden event, there were 3 major terrorist attacks, one at the white house , one at the pentagon , and one at NASA. you later discovered that the person who spearheaded the attacks is none other
than the escaped General, who manipulated the minds of the terrorists, giving them advanced arms and inspiring them to go on suicide missions. Dying for revenge you atlast succeed in defeating the General, and restore order on Earth.
