Help with The Ultimate Torment & Torture arena

Hello!
I am supposed to kill these two cybers to get out ... but I ran short of ammunition. Is there a trick or some hidden armory?

Thanks!

Uhm... I remember I played the original level (not the version in UTNT) and I remember I had a problem like this. Maybe you should have exploited infighting when monsters keep teleporting in that arena...! If so, I hope you have saved the game before entering that arena.

I see Hitler in that skybox :S

Don´t remember that level, but here´s a cheap trick for you: open the console and type: give ammo

Good lcuk

If I remember rightly, after you progress through all the waves of monsters, a switch will raise itself out of the ground, and when you hit that switch, it launches a whole lot of rockets or plasma or something out of those two holes near the cyberdemons, and kills them.

I think it was that area.
