2 pc's 1 copy?

I have 2 pc's do I need to buy 2 copies to play the game on both pc's or is there a way to run the game on both pc's at the same time with 1 copy. Have not even tried it yet just wondering. Thanks.

Game is not shareware yet, so no. Maybe in 2035, no wait wolf 3d released 1994 is still costing money so probably not in a while longer. Steam sales will probably have a good discount when NWI releases the next game though=)
