Carpenter

Carpenter is a power-up found only on the Zombie map, Der Riese, in Call of Duty: World at War but in Call of Duty: Black Ops, it is found in all maps except for Dead Ops Arcade. When collected, the demonic announcer will say "Carpenter" and it will completely board up all of the windows on the map. Carpenter also awards a 200 point bonus to all players when it has finished boarding the windows. It is symbolized by a floating hammer.

Tips

 * This power-up becomes extremely effective on later levels of the game. While it won't kill the zombies like a Nuke will, it will stem the tide of all the zombies by forcing them to reopen all of the windows. However, during the late rounds there may be several zombies opening the same window at the same time, so it will only slow them down for a couple of seconds.
 * Carpenter does not instantly board up the windows. It appears to work similarly to the Nuke in that windows closer to the power-up will be affected first, with the effect traveling outward.
 * The point bonus awarded by Carpenter is affected by Double Points, along with the Nuke power-up, but only in the Black Ops version of zombies.
 * Sometimes, it is best to save Carpenters until the player wishes to keep a zombie at the windows instead of the common strategy of making a crawling zombie so that the player will have time to get weapons and perks.
 * This is a very good power up for players utilizing weapons with long reload times, and for groups online, as it allows them to reload and prepare for the wave of zombies that inevitably follows.
 * There is a glitch when using the Carpenter power up. If you grab it when a zombie crawling through a window, the zombie will instantly die as soon as they step out of the window. This is probably because the boards crush it down.
 * Sometimes, when you have a crawler already made, Carpenter isn't the smartest choice as you might get more points out of manually re-boarding up the windows.
