The difficulty is not comparable to rebuild 1. I did finish hardest difficutly without the need to reload (I did reload because I wanted to but not because I had to). And yes I did finish Rebuild1 in the hardest difficulty and you did need some skills reloads and luck, in Rebuild2 you just need one of the 3 instead of all 3 ;).
I did start Rebuild2 on hardest and finished it right away. I only started the easy one first because I did not see how to change difficulty as I was just clicking through.
Rebuild 1 was much harder I did like that however it is interesting with the new things in it although the UI handling and controls for these should get some improvement.
@KingAquarius if your timing is right you can do it only with 3 mirror images. I got it like this. But yeah it is a nice game and the last stage is very tough.
Funny game.
Actually it is more luck or it just takes damn long till you have enough nukes to nuke him from start to finish which is basically the safest way to do it :).
Nuke till he gets too slow then shoot him and nuke again etc. .
I did it before I got all medals.
