Black ops 1 is a old game some people say it the best black ops game.
its exactly like black ops 3 and 2 but the graphics and stuff are worse.
the multiplayer in it is really hard and the zombies Juggernaut is bad .
zombie maps are harder and original but some where stolen from waw.

the wonder weapon is a gun that blows all the zombies away and doesn't always kill them but its really good.
