like me, most people are going to struggle with and have a hard time with getting 25 guardian kills. my first time doing this was for the solar sword back when quest first came out, and at that time shotguns werent used like today, so getting sword kills was much easier. today however...just getting heavy ammo 1 time per match is lucky. so i completed the 25 heavy weapon kills today, by playing supremecy and killin. with the hilt when i could. its hard, since everyone uses shotguns. i had to be sneaky n'flank the enemy n use heavy ammo wen available. GL!
