At the start I loved this game. Great fun for the first few missions, but the improvements needed really affect gameplay negatively. The most important is that you have no idea what you are looking for. The mission briefing should include pics of what you searching for. Second, on one level (oil barrels), I have searched over 3.5 hrs far and wide for the targets without any luck. 3.5 hrs of fruitless gameplay really loses my interest in continuing a game and makes me want to move on to something else.
My star-rating is based on overall experience. At first I would have rated 4.5 stars, but the frustrating lack of results in gameplay has me lowering it to a 3 overall. Hopefully the design team read these comments and make some changes.
