Well tokyo is a very hard to navigate level there are hidden rooms
ok when you get all the hostages theres a road way go to the far end of one of them theres a door use it you then have to get past these canons to battle a flying dragon.
I will post some photos of it sometime
Argh, this game was stupid hard. Once I used a cheat to try and finish it, but I think there was a bug on the Tokyo level cos it was impossible to get any further. You had to rescue all the hostages but at least one of them was unfindable. Disappointing, but it did have nice graphics.
