TF2 map set in an abandoned industrial estate, taken over by an evil mastermind! The gameplay is slightly different to the stock TF2 maps, in that there are two capture points, which you can take at any time (they never get locked).
With Fortress Forever finally out and and revitalizing my interest in Team Fortress, I decided to remake my favourite TFC map, Duality. Lots of tweaks and extra detailing to bring it up to Source engine standards. Should be ideal for all those fledgling FF leagues
