Call of Duty: World at War

Start a level of Shi No Numa by yourself, during the first round make sure that no zombies gets in, after the last one is tearing away at the window, stand in front of the window (Not too close, the zombie will attack you) and Hold X, this will make you repair a board every time one gets broken down. The zombie cannot get in this way. Keep doing this until the achievement unlocks. The easiest way to unlock this achievement.

Whilst playing the Shi No Numa (Zombie Swamp) map, various places around the level will have boarded up area's designed to keep zombies from coming to get you, except it doesn't actually stop them, it just slows them down.

When a zombie removes a board you will be able to put it back up again by holding X near where the boards were before they got knocked down. You will do one board at a time so it can be a tricky one to get.

The easiest way to boost this is kill every zombie in the first round except one, let him tear away at a window and then you stand next to it and hold the X button to put it back up. Be careful though that he doesn't reach through the barriers and try to grab you as this will hurt you but you can easily step back if this happens. Just keep repeating this method until it unlocks.


If you want to get this legit then my advice is to board as many windows as you can up between rounds - make this your main objective if you are solely going for this achievement.

Another good tip would be to allow the first few waves of zombies to completely tear down as many of the boards as they can - because the first few waves are always relatively easy, you can board them up as you take them out and afterwards.

Finally, if your at a point where a lot of windows are unboarded and you are certain that there is only one zombie left, allow him to follow you but don't kill him... this way you can go and board up as many windows as you can before taking him out and carrying on.

On the first round, kill every zombie except for 1. Wait until the last zombie gets to the window and DO NOT HURT HIM. Go the window he is at and hold down the repair button and he will keep pulling down the boards and you will continually repair them. This may take 10-15 minutes.

very easy just play by yourself and leave one zombie and as he takes down the wood just keep building only takes about 10 minutes

Start a Nazi Zombies game alone on the Shi No Numa map.
Once in the game, make sure no zombies break through the boards. There is 4 zombies on the first round so kill three and wait for the last one to get to some boards. As he is pulling the boards off, press and hold X to repair the boards. As you put one back on, the zombie will pull one back off. Just stand so the zombie cant hurt you and wait for the achievement to pop.
