During the course of multiplayer you level up characters, unlock characters and unlock equipment and so on, and I know that multiplayer is apparently tied in to singleplayer.
So, does progress made in multiplayer link to a related single player run (so if you start another play-through does that play through track its own progress of multiplayer unlocks, etc) or do you have a single multiplayer 'profile' shared by all single player runs?

the multiplayer affects the galactic readiness which makes it easier to get the best ending in singleplayer. the readiness stays the same through any sp playthrough and decays at a rate of 1% a day until it reaches 50%. the levels of your mp characters dont affect the readiness, but you can promote a level 20 character into single player for war asset points.
