This is the only release of DX coop, no further development will come since the project is dead.
RolePlay Coop is a modification that adds cooperative gameplay mode to the first Deus Ex game.
This mod lets you play the SinglePlayer missions together with your friends. Gameplay is unchanged: there is a main protagonist, persistent storyline, resources are limited and every living being has only one life.
To keep the immersion on high level and storyline intact this mod doesnt introduce any characters whose presence could conflict in obvious way with the story.
The world of Deus Ex is populated with many non-player characters. Unfortunately all those characters have very limited dialogues and action sets,there's minimal amount of interaction. Have you ever wondered what would some characters do or say if they could do anything? Would they help you and how? Who are they, what skills do they possess, what's their story?
RolePlay Coop revolves around those seemingly non-important characters.The main protagonist has been given an action he might have not considered before: asking common people to help him. Those who will agree to help him can be controlled by the real players. What will they do and who they will be is up to you. NPC characters can now walk out from the shadows and make a difference in the Deus Ex world. In the real world you and your friends can experience a truly unique adventure.
That is the key difference between the RolePlay Coop mod and typical Coop mods. There is no army of main protagonist clones or anonymous characters. There is JC Denton and all the people who inhabit the Deus Ex world, more human than ever before.
