This guide will make it all easy. Even for one person. Heavy Metal Solo *air shreds!!!* - Xbox360Achievements.org Worked on my first try. Never even died. Could'nt make it past level 12 before it. If anyone needs any help, send me an invite & we'll do it. Had around 5,ooo pts at lv14. Kept a cloaker alive and went around unlocking all the weapons for the other people. Only used an overshied twice but never really needed it. Used main gun & null ray. Did'nt follow the guide completely, just made cloaked ammo & health runs 99% of the time. Even took a piss during the match since you can't pause.
