Streets of Rage 3 is certainly the hardest of the trilogy. As far as I recall, I’ve only completed it once before, and then I don’t think I got the best ending.
And so it is that I didn’t get the best ending this time either, unfortunately. I reached the chief in Stage 6 too late (and only just too late as well), and so Shiva was the final boss for me. It’s frustrating, as I played through the game three times today, and on the second attempt I did save the chief – then died on Stage 7. On my third and final try, I didn’t save him. Annoying.
Streets of Rage 3 probably isn’t as good as Streets of Rage 2. It has lots more moves, bigger sprites and in some parts (like the disco) some incredible graphics, but SoR2 plays better and has more variety and much, much better music. Also, Zen (in 3) is rubbish. Where has Max gone, anyway?
