Fun game though fairly easy to beat
This is a nice game to blow and hour or so on. I like that the solider and cop zombies are wearing vest - so shooting them in the legs is the best option - plus the mix of runners, fatties, dogs and a clown (funny) give a decent mix up of foes.
The spending hours to search for weapons or people or fix the base is a nice change from a standard survival game.
However, once you get the shot gun, the game is realtively easy to win. Using the "change gun" option you can quick load the shotgun to avoid the pumping action then switch back to the shotgun to save a lot of time. Of course the berreta is game over with the ability to kill no only the enemys behind the targets - but some to the sides (several feet to the sides). I found that the base never really needed to be repaired - lowest it got to was 85% throughout the duration of the game (no fixing).
