Fixed the horrible spelling and grammar on this. Mostly non-canon, or speculative.
Mistake?
Can't be sure but I'm 90% postive that on all difficulty levels both cannons can be fired, this line contradicts this - "Only one can fire at a time." Any thoughts?
Error
The part where it says that the covenant never saw a monitor is false. In halo contact harvest, they find a monitor, and start the entire war over what it said.
