pretty good summary

The maus's weaknesses are the lower front plate and turret cheeks, as well as its flat sides and slow turning. The turret weaknesses can be negated by angling the turret properly (something I cannot yet do with the Mauschen), and the LFP can be hidden, rocking the tank also helps.

The Maus specializes in breakthroughs and acting as a sort of blockade - it can, with minimal support, hold a position indefinitely, remaining virtually invincible as long as it is not swarmed. The exceptions, of course, are the Japanese superheavies.

I'll probably have a Maus within a year though, so I'll know more then.
