Middle-earth: Shadow of Mordor content will be similar across all versions of the game, however, the Nemesis system will scaled back on PS3 and Xbox 360.
Speaking with IGN, design director Michael de Plater said Monolith's primary focus is on current-gen systems PS4 and Xbox One. Then, the team will do whatever it can to "get as much as possible" on PS3 and Xbox 360.
"We're very focused on the PS4 and Xbox One," de Plater said. "We're focusing on the next-gen platforms, and then going to do whatever we can to get as much as possible on current-gen.
"To break it down, some of the stuff we're pretty confident will still be very similar on current gen: the core mechanics, like combat, stealth, ranged and movements; the basic control and gameplay, that should all be really solid. What it won't have is the same level of depth and variety and simulation within the Nemesis system.
"The story will be the same and the core gameplay will be the same, but the Nemesis system is just so huge in terms of content, calculations and AI we'll just have to try and get as much of it in as we can."
Middle-earth: Shadow of Mordor is due in 2014 for PC, PS3, PS4, Xbox 360 and Xbox One.
