Olaric is unkillable

I used up all the ammo I had plus whatever I found in the level. I even threw knives at him. Nothing works. Is this a bug? I'm playing on the Death Incarnate

I killed him yesterday on Death Incarnate, takes A LOT of bullets, the gate he enters from, if you go down there and to the right corner of the building on the left, you will find a rocket launcher (panzerfaust), use that carefully along with all other weapons, spam those bullets till he drops dead.

There’s no Panzerfaust there. And even if there were I doubt it would have helped—not after I’d already used up all the weapons I had and I had gathered a huge amount.

I was using 2 dynamite packs, then the shotgun. Wasn`t that hard.
Also got a prize panzerfaust for finding all secrets on some crypt level, might help too.

Here’s how I did it: I replayed the previous level using only the pistol trying to preserve as much health as possible and also found the crystal skull—after which the game gives you dynamite. You can defeat the boss using all of this but even then it’s not easy

Which Olaric we talking about?, The one in the elevator section( which can be hella cheesed) or the one in the courtyard.

Found this gem so I thought I'd play it since I enjoy all Wolfenstein games. It's been a while but I can not get past Olaric. I did unlock Panzerfaust in the crypt but there is no PF left of the bulding. I used dynamites , granates and exactly all ammo ( I had full) but he is still standing.
I watched a youtube about killing him in RealRTCW but basically it's just one dynamite and maybe 10 rounds of shots and then he is history but that is so not happening.
Any other hints on how to take him down?
