The Yeti creature is used for the Karlam demon; it is often modified in many mods/maps. Although, in principle, the map can be made compatible with EWA, as NCF is present there, if I'm not mistaken(?)
and the EWA settings (mine) that I used to play with

I hope you will somehow create a continuation (analogue) taking into account (the game's progress). In the old version (without EWA, I think only Remix is played).
