Most of the models and some sounds I think were ripped from the Quake2 TC "Dawn of Darkness". They claim to have gotten permission. Other content was apparently appropriated from Hexen2, Heretic2, and Fantasy Quake. Tomaz did a lot of engine work for them but they didn't pay him and he burnt out. Some other guy finished the last 5% of the engine and got the credit. (leileilol probably remembers the details better than I do.) At the time the company was called "Two Guys Software", I've never heard of "Xrucifix". The people who led the project came across as jerks trying to make money for themselves without doing any work. The Christian theme was some niche audience targeting that only surfaced in a few text printouts in the game, probably. (And they say that because you are killing demons, it's all good. Well, by that logic Doom is a Christian game too.) I personally think the mod is worthless (no offense to Xsniper and people who put honest work into it). Dawn of Darkness for Quake2 is a hundred times better.
