Nice video we got here) Pretty atmospheric too.
Fun fact: During the development me and my friend were testing Hell from Earth with Arachnocide Weapons im zandronum multiplayer. I missed where Arachnocide wasn't invented for Zandronum, so we were playing with INVISIBLE ammo and weapon pickups. Only on tenth map of Hell Revealed we started to suspect that something was wrong...) So yeah, Arachnocide Weapons is good with HFE)
