To be honest I didn't see much that was unique about the new weapons, they basically are just variations of the original ones. You are introduced to a couple of new enemies and new weapons in this expansion. I didn't find myself getting lost constantly like with the main game, so I can surmise that the flow of the levels is better. The one thing I will say however is the level design seems somewhat improved. The environments are mostly just recycled game assets and textures from the main game. Overall, I would say Return to Na Pal is basically 'more of the same' and doesn't really offer anything new. I suppose it could be an issue with Wine?

I tried to find a work around for this but haven't had any luck. For some reason the audio logs do not work properly on my game - some of them play, but a lot of them didn't. Return to Na Pali is the official expansion to Unreal released in 1999 and is a direct continuation of the 'story' from the original game. This is a full, blind play-through of Return to Na Pali on Linux Wine.
