CTF-Niven2051

This is the remake of the old Unreal Tournament map CTF-Niven. It was one of my favourites in UT99. I tried to use as many ut2k4 content as possible. There is no new textures only the round corridor meshes had to be done custom.

I tried to stay as close as possible to the original ut99's layout. But it should not look like an outdated simple copy. I replaced the razor pickup by another minigun pickup. It didn't make a lot of sense to have different weapons in the bases anyway. I added a full walkway leading around the upper part in the center to make this part more interesting. This is the only change to the original layout.
