This game has a lot of improvement compared to its predecessor, such as:
+ Open world, I really like the idea of exploring around.
+ Upgrades, it is very well done how you can upgrade yourself through the game.
+ Achievements, you feel more rewarded since more achievements are available.
+ Characters: The new Latin guy is a really good addition as well as the new IA.
+ Story: the story is really well elaborated, similar to its roots (however, could be more depth and more huge). Specially de music or soundtrack... great..
Where could it be better (spoiler alert) only it is a matter of taste:
- Being a Sci-fi game means be in different places around in the galaxy / universe... During this game, I was expecting more places to go in addition to exploring the same place... the game has good cinematic but it feels that need more of it to back up the story.
In summary, a most play. Highly recommended. Enjoyed every second of it.
