I downloaded the game. It was alright; and it's always nice to see something other than a zombie game every now and then. Unfortunatly, the 5th(?) level does not load and the game crashes after that ("object line not found at...").
Everyone already mentioned that it needs lightmapping so there's no point to add anything else to that. But the AI needs some work as well. All I did for the first two levels was walk along the left wall all the way down to the win zone...they never even saw me.
You should also try to stick to using weapons that all use the same player hands. It was sort of strange holding a sword with a knight's arm in an Egyptian game, and then grabbing a modern day combat knife held by biker gloves
The last thing that stood out to me were the residential wooden doors in an egyptian cave. Anyway, with a little more work, it looks to be an interesting game.
