i have 384... how did u beat mw3 5vs1 on hardest settings?
Build a custom Annihilator with max armor, minimum engine, and all the LRMs and heatsinks you can possibly cram onto it. Stay near the shuttle, wait for one of those Clan fools to come within range, and start unloading salvos of LRMs on them :evil: Use your coolant flushes to bring the temps down as needed. You'll take some PPC strikes but you'll easily outlast them if you take the standoff approach.
Plan B: equip your 'mech with jump jets and get up onto the rim of the "arena" there, then snipe them at your leisure with LRMs, lasers, whatever you like best. You can actually go roaming off into the tundra or even toodle back down underground to the mech factory.
Plan C: build a fast Annihilator with four LBX10 autocannons, plenty of ammo, and max armor and just wade into 'em. :evil: Circle and keep moving. If you want, you can make a sortie against them to lure them, then duck back into the cover of the shuttle nook and wait for them to arrive so you're not exposed out in the open in the meantime.
edit: a couple AMS's might help too.
