Not as good as the original.
Anomaly 2, the sequel to Anomaly Warzone Earth is a good game. The shame is that it isn't as good as the original part of this series.
Not from the technical standpoint, that's for sure, because Anomaly 2 is a beautiful game. It's attention to detail is really good, artistic design is great and graphical fidelity is more than enough. Even the music is good, and the voice acting is better than in the original. Only flaw on this side would be the UI, that despite being quite minimal, sometimes gets confusing. There are times when it's hard to see which health bar belongs to whom. Anyway, that's just a minor flaw.
Its main problem is that it starts slow. Too slow. First levels are pretty dull. Specially if you played the previous game. It spends too much time being a tutorial. And it's a shame, because it's easy to get bored soon, too soon. Then everything gets better. Then its difficulty gets higher, new towers appear, the game stops treating you like a newbie, and the fun begins. It's a shame it needs more than an hour to realize you are ready to roll. An hour in a game which lasts about 4 hours? - I'm in mission 9, of 14 I think, and I've had 2.5 hours of actual gameplay, so I think 4 hours for the single player campaign is a pretty good guess. That's its mistake, and it's a big one. But once you pass trough that, things get really cool again, like in the first one.
As for the multiplayer... I won't say anything about it. I'm really not interested in it, and I didn't even tried it.
Don't get me wrong, this is a good game, but it would have been better not spending so much time being a tutorial. Maybe it's just me, but I love those sequels that assume you have played the first one and/or you know what you are doing. Anyway, mechanics are not intricate or anything that justify so slow learning curve. Everything is pretty straightforward and easy to learn.
Do I recommend it? Yes, but with a bit of caution. Bear in mind that it could disappoint during the first missions.
