Freaking awesome!!!
That about sums up my first impression.
I played through the DC story line and started up the MK side tonight. The story really works and the way it’s layed out is great too. The fighting mechanics are fun fun fun. The new klose kombat and free-fall kombat are a new and fresh addition. I’ll write up a more in depth review of the game after I’ve put enough time into it. For now I’m just enjoying it to the fullest.
