Proving Grounds is a TDM modification for Natural Selection 2. It focuses on First Person combat, without the RTS elements of the full game. Currently in alpha development, the mod will eventually feature multiple modes and full customisation of characters and models. This will be updated as more media becomes available.
Here is a mapping alpha to provide mappers with an idea of the basic movement and to enable them to build to allow for Jump pads etc. Things are still a bit buggy, but the basics are there, tweaking will follow down the line.
