I love this game.
Without the hidden missions it is a hard game of survival and tough decisions that even at the best of times can lead to your inevitable demise. The game is so involving for everyone and often sparks debates over rations and actions...Now throw in the hidden objectives and OMG the traitors and there is a constant questioning over every move you make. Do we really have enough fuel to survive or are we looking at being overrun...
My advice is always go to the police station first because having a weapon makes the game so much easier, the truck driver with a shotgun is freaking awesome. The police station, gas station and grocery store are always a must in all the games I have played.
