I went into the gunrunners place and vendortron came out of his little cage and starting attacking me. He hardly hurts me, but he is invincible... he is now the hardest enemy in the game.

Woah woah woah.....How did he get out in the first place O.o

he's actually the last boss of the game. there's a little-known 5th option of siding with the Gun Runners and that Vendortron actually grows to the size of the Lucky 38 and stomps on Hoover Dam.

How did you get him to come out? Ive killed all the workers inside and the vendatron would stay inside and still sell me guns.

He bugged out of it. Theres a little oppening on the side of his cage and i threw some nades in there and he got suppperrr pissed and i entered the gunrunner building and he was in there.

lol

I've done everything except drag a 200 year old nuclear warhead to that little shed and set it off trying to get him out, and I've never been able to. :sadvaultboy:

Primm Slimm, another Protectron, actually has 2600 HP at level 35. This makes him 2.5x as hardy as Legate Lanius. So, outside of bugs, Slimm would probably be the most difficult enemy in the game. Or Graham, maybe, with a DT of 50. Hold on a sec- Primm Slimm Vs. Joshua Graham! Somebody has to set up this fight!

OMGOMGOMG I want to see that!

However, let's be serious. Joshua is packing. Slimm isn't packing. A .45 pistol will send anybody home in a bodybag.

Benny thought 2 9mm rounds would send anybody home in a bodybag.
Caesar thought being set on fire and thrown into the Grand Canyon would send anybody home in a bodybag.
Boone thought a .308 round to a pregnant woman's skull would send her home in a bodybag.
...
2/3 isn't bad.

I'd rather deal with Joshua than a pack of giant cazadors(Antidoteless) personally. Flying menace is what they are. Especially on Very Hard.
