Heihachi is still alive coz u he is a playable character check www.tekkenzaibatsu.com
I bought it yesterday.. so far its great.. my only complaint is that you know the training tool in tekken 2? they go through the correct button presses as you do them.. they only half half of it in t5 (they demo it for you but wont keep the button presses on screen as you practice them) .. other than that , this was the tekken I was hoping for
Not much loading time, which is great. Some of the endings are kind of silly (Lee's ending was hilarious) and some of the midway dialogue was humorous too (i.e. Kuma's path against Paul). I have all the endings, except Devil Jin (I think it's activated from the Devil's Within mini-game) and I'm still waiting for a walkthrough to see if I missed anything else.
