Concrete trap

Description
The immortal blockade!

Tips

 * It is best to create this barracade at valuable entry points for the zombies, namely where they are coming in the most.
 * If a fellow survivor is trapped or just behind this barracade, it would be a bad idea to call them as they would tear the barrier down!
 * If one would search all the time for trap parts with Jack Foster, they may be able to block off the safehouse.
 * As above, one can completely block off a safe house so one may explore the same safehouse.

Trivia

 * Zombies can still be heard fruitlessly trying to break in.
 * As above, it can be seen that as they break in they act as if was a basic blockade.
 * This barrier gives the possibility of RPG play.
