Eidos has recently gone on record to state that the Xbox One and PS4 version of Tomb Raider, will have some new features not seen in any other version, dispelling any talk that the game will simply be a PC port. The Xbox One version in particular will see some optional voice commands which aid in navigating the menus, and switching weapons on the fly.
Speaking on the Tomb Raider Forums, Scott Amos of Eidos posted the following comment:
“The work that went into the PS4 and Xbox One versions started at the end of the X360/PS3/PC versions. They were our foundation that we then built on top of. The amount of extra work – 3 studios and a full year of development – have pushed the boundaries beyond just TressFX and upgraded textures. We now have a new particle system, new lighting work and enhanced shadow-casters, tons of more visual storytelling elements (more debris, more details on walls, more density in the environment for vegetation), upgraded characters (Lara and main story NPCs), and we’ve also put all of the DLC materials into this version for PS4/Xbox One. We are very happy with the PC version we released and felt these new additions and changes were something custom just for next-gen consoles at the moment.”
