credits go to the team that made the lovely scarab, and the guy who did the Non Rebuilt Island, and bungie of course.
I made it because, hell, a scarab vs an airforce of shees.
anyways, here's a pic I took,

and one I took when we screwed up and the enemy took our scarab and started bombarding our base,

all the weapons are changed, and not changed as in replaced with CE, but modded the good old fashioned way.
plasma rifle shoots a purple streak of lightning that stuns and repels enemies away,
shotgun shoots little firecrackers that imbed themselves into enemies and pop,
pistol shoots little flammable pellets,
sniper is an anti-anything sniper,
AR is just a more accurate AR
and the banshee is equipped for fighting the scarab. It's guns are replaced with twin machine guns, and it drops missiles.
oh yea, and it flies a damn lot faster than it used to.
anyways, I played this mod with my friends, a 4vs4 server, had a hell of a time, hope you guys do, too

PS: for the blue team, the way to get into the scarab is by taking the teleporters in ur base.
