I don't know about the mechassault version, but my version came with Mrs Pac Man, but you can't play it off the disc. It just enables you a free download of the game. The whole point of live arcade is to enable you to download cheaper arcade, sports, puzzle etc games directly to your HD. So yes, you would need live to get any value from that disc I believe.
