To make a mod that not only looks like halo, but also Feels like halo, would need the inculsion of several mechanics, such as recharging shields, jumping at a height of over your own fellows, plasma physics for the halo weapons, and many more.
Unfortunately that is a ridiculous amount of work, when you could just urm, play halo. lol
i am a huge halo fan. but id sy the job would be too large to be successful in all honesty, and it wouldnt have the same feeling.
I KNOW!!!!!!!!!!! A SONIC KF MOD! lolol i jest.
