Guerrilla previously planned on-the-rails Move version of Killzone 2

Guerrilla's Tommy de Roos has said that Guerrilla was once planning an on-the-rails shooter version of Killzone 2 featuring Move.

de Roos made the admission in an interview with Ars.

"When we got the initial [Move] prototypes, we had no set plan on how to add motion control to Killzone. Being a first-party Sony studio, we had little experience in that area except for some small experiments with the SixAxis controller," he said.

"One of the first ideas was to create an on-rails version of Killzone 2. But once we realised how much work that would be, since all encounters would have to be re-scripted, we decided against it."

Killzone 3, with full Move support from the get-go, releases on February 22 in the US and February 25 in the UK for PS3.
