Halo 3000 review

Ok this story is about an elite team of spartans who are traveling the world to kill the Covenant leader in hopes to save the human race and to destroy the covenant what they dont know is they are facing something that is nearly impossible to kill
thats one idea of mine or it can be a comedy series about a team of spartans who live in containment or zanzibar suggesations are needed of chacters names or what maps for it to be on
