Boomer

The boomer is a big zombie which walks around slowly and attacks you. Even though they act as a normal zombie when you kill them they start to change color until they turn red, and then they explode, creating a huge noise disturbance which attracts more zombies. So it is better to avoid them during day time unless you want to grind EXP. Be careful as the explosion causes a lot of damage and also damages your placed items.
