Postal has no pretense of depth in any way. It knows what it is and boasts of it: an assault of continuous, gruesome violence and carnage, bolstered by many loud, painful and messy ways to kill and die. It's not the kind of game that will immerse you for months, but it certainly is the kind of game that will make you laugh out loud at the same time as give you a twinge of guilt for enjoying such brutality.
