So give this game a few hours and as simple as the graphics are, the game play is awesome. It is challenging as well as fun. Did almost 5 hours all at once. The scanner is the best way to find your oil fast and then if you are low of funds I use the mole. A lot of the upgrades are not worth it, but you won’t learn that until you try them. But that is part of the fun of the game. Really enjoy clearing out everything each time, and ending the round right before the time is up is a great way to make an extra $1000. This is a non-violent game which my son will be reviewing on his radio show next week. (The Tiberius Show) This is safe for kids to play and a great way to get them to compete to see who can get farther faster. Great job DEV team.
