The whole point of the game is to take the mick out of Rednecks really. This isn't the calibur of DOOM or Half Life or even Postal 2.
Becase it's even less of a game as Postal 2 is.
This is just simply some daft fun, you run around wasting the enemies trying to find the exit before you move onto the next level, all the while you're listening to some cheesy awful Redneck songs that are funny because of what they are.
So if you're just after some simple fun, get this. Unless you don't have Postal 2 yet, because it does simple fun A LOT better.
