Defeating Mister Freeze

After helping Mister Freeze steal a bunch of diamonds to save his wife, you eventually have to turn on him. Not sure if you kill his wife or just prevent him from curing her, but either way he's not too happy about your 'treachery' against him. Mister Freeze is quite a difficult opponent if you are on your own and it doesn't help if you're the same level as the mission or lower.

So you start exchanging fists with the ice man and he then he calls his goons and magically after they're all gone (from you pounding them) he has all his health back. "Damn it, I knew I missed out on something!" you say...? Well threat no more, here's The V's help guide to shattering some ice cubes and smearing some frosting on a cake.

Smack Mister Freeze around a bit and then when he calls his goons, make sure you kick the fat ones butt first! When Freeze calls his goons to come attack you, one of them is Freeze's Medic Man. He's really called a freeze regenerator or something similar, you cant miss him, he's the fattest goon there. Attack him first and stop him from getting to the cylindrical device which is next to an icy circle thingy that Mister Freeze is now standing on. That's what heals the ice man so make sure he doesn't get the chance. After killing the fat guy see to it that the other two don't kill you before you kill them, so knock em dead!

After a few repeats of this (about three if you're good) Mister Freeze will eventually fall down defeated and you collect the diamonds off of him. So in defeating Mr Freeze you should focus on a lot of ranged attacks and only go in for face to face combat when you have the upper hand or advantage. A lot of stun attacks help. Make sure you have plenty of sodas on you, there are health barrels around but you never know when you'll need them. Sometimes a soda is just easier to get to.
