This page details bugs of Proto:ICO/US Preview Version.
Cutscenes#
- Ico is supposed to hold a stick during this flashback. However, it seems the cutscene map fails to equip it to him, leaving his right hand empty.
Encounters#
- If Yorda was left alone and abducted in an adjacent stage, but promptly rescued, the next area entered may have shadow nests from a prior scripted fight briefly emerge, before dissipating again.
Effects#
- When pausing or saving the game, glow effects that surround both the stone sofas and cylinder switches (found by the Idol Stairs) suddenly vanish.
- Additionally, the brightness of the sofa glow is meant to increase very gradually as Yorda approaches them. But as the images above display, one single step into their radius causes the dim glow of the object to appear very suddenly over the arms and seat, rather than fading in subtly.
Other#

- After being defeated, specifically in the boss fight with the Queen, Ico's stone form vanishes at the moment the 'Continue?' screen appears.
- After Ico lands the final blow against the Queen, a cutscene plays where he loses his last horn. At the tail end of said scene, you can hear Ico making attack grunts rapidly, off-screen. This is not part of the cutscene audio in the game's files, which might imply that Ico's gameplay model gets stuck repeating the last input it received.
