This game tries desperately to make up for the previous title, 'Chrome', which had interesting ideas, but poor execution.
The god-awful combat from the first game has been fixed. Sort of. Not really. On the one hand, the enemy is no longer super accurate while your aim is all over the ♥♥♥♥♥♥♥ place. On the other hand, enemies are still dumb as a box of rocks.
The environments are, like the first game, big with lots of open spaces with wild animals foraging for food. It's a nice detail. It would have gone a bit better had they not simply reused so many of the assets from the first game. Add to that the blandness of some of the scenery... it's not very exciting to look at.
One of the biggest gripes I had with the first game was the designed-to-be-useless inventory. In the previous game, you couldn't carry more than two firearms. Now, you can, but it still retains the basic architecture, which is limiting. Still, it's improved.
I'm not sure why the enemies you fight have to be wearing the same sort of armor you and your team wears. It's weird.
The missions in this game seem more concise than the first game. The "tutorial" mission from the first game was unforgiving. Here they tried, at least, to introduce all the major concepts in the first "tutorial" mission, which is a cakewalk. I still find the implementation of the neural implant system to be archaic, but whatever.
It's sad to say, but the game still has a generic feel. I mentioned earlier that it recycles many of the assets from the previous game and, unfortunately, that includes the terrible facial models. Everyone you meet looks like they are missing a chromosome or two. The upside is that the voice acting is improved from the first game. The real problem is that there is no emotional investment in the game. For the sort of game it is, or tries to be, it simply lacks the characters, interaction and fascination that you find in games like Deus Ex or Halo (for examples).
If you are an avid FPS gamer, you may find something in here that you enjoy. If you're a more casual, or discriminating, FPS gamer then this probably won't do it for you.
