Cry.Sys is a cancelled action game that was in development in 1995 by Sierra, not related in any way with Crysis by Crytek. In Cry.Sys we would have took the role of a virtual reality robot, to fight against other mechs to save the last girl on the planet, trapped in this weird cyberspace. Sierra planned to have an editing feature to create our own robot and an online multiplayer mode. For some reasons the project was never finished and only a short preview from NextGeneration magazine issue 12 and a CG trailer remain to preserve its existence.
Thanks to Celine for the contribution!
