Old infection maps camp spots

Remember, when reach had these unkillable spots in their infection maps? I know I do, I forgot most of the levels names but I remember camping on this one map for like eternity (until we ran out of ammo that is). It was also the time I got the achievement where you had to melee a infected player after your ammo was out.

I still like how it is, except how they added some stuff like invisible golf fire zombies (I honestly don’t get why they made that, along with other ones).
