I downloaded this game a few months ago. It was around 550MB. I played it for about a couple of months and I would like to share my experience.
First of all, one very disappointing thing is that this is not an open world game. In fact, it is a very closed game without many stages. There is only 3 arenas or 3 setting where you play the game. All of the levels are set in those same places and that is why it gets very boring very fast.
Another turn down is that almost all of the missions are very similar to each other. Sometimes you have to snipe a person on an airport runaway to prevent plane from taking off, other off you have to provide cover fire, but that is it. You have to play only these kinds of missions throughout the game.
Another very big thing that I dislike about this game is that it uses Energy system. You can play until you have energy bars but if you run out, you have to wait to play again or you will have to spend real money to replenish your energy bars.
Another thing that is not well optimised are the controls. Tilting and turning while zooming using Sniper Rifle is very tough and it would have been very easy if the controls had been better optimised.
I would not recommend anyone to download this game. Thank you.
