This applies to the 1 as well as here the 2nd part alike. Although I personally found the 2nd even better. He came round to me and even more epic as the front. 1
Both are an absolute must.
One should not only own the game the 2nd part spoil where you would expect the exact same features as the 1st. Personally, I find the changes good and refreshing.
I have both parts played in succession. A short familiarization time was there, but after a while I began the new control / implementation to love. :-)
Much has already been said here, so I'll keep this short.
An absolutely ingenious action sci-fi game with little RPG deposits. Epic story to cheer, great fights and a absolutely great moderate Soundtrack.
I'm looking forward to the 3rd part!
