Not a game of the year by any means but way better than a 5.0 leads you to believe.A good game for mindles mayhem.
It's a hack and slash.So if you are looking for depth than you've got the wrong game.It is just a fun excursion from the huge wave of Sci Fi games and FPS's.Plus chopping of heads and arms is always fun!!!
One of the biggest complaints is that it is repetitive.However it's only as repetative as you make it.If you just want to charge in and kill everything every time (witch is fine).Then I can see how that would be the case.If you take the time to find the locations and scout them out you will find that there are other ways to handle the freeing of your army and other tasks with stealth.
As you gain money you can buy new attacks to help along the way.All are very easy to learn and start using right away.The major fault in the game for me was the inability to find new items.You upgrade your weapons a couple times in the game but they are the same weapons just more powerful.
So at the end of the day I would say to rent this game because it is a good time.If you are thinking of buying.I would hold off until you can get it used or they drop the price.I would also add that you may want to play on the hardest difficulty to make it more challenging.
