Biohazard 4 (Hallucination Version)

Hallucination "biohazard 4" (幻の「バイオハザード4」) is the third build in the Resident Evil 4 development, succeeding "Castle". It is otherwise known in the West as the "Hooked Man version".

Gameplay
The game displayed numerous elements that have were carried over to the final release:


 * The over-the-shoulder perspective when Leon's weapon is drawn. However, in the video, there are a few times when Leon aims without the over-the-shoulder camera. The game reverts to a third-person view like a traditional Resident Evil game.
 * A red laser sight for Leon to use while aiming.
 * Leon being infected.
 * The flashlight that is added to Leon's character design.
 * A suit of armor suddenly attacking Leon when he attempts to pass it, as well as the button combination to dodge the attack.
 * The ability to throw a grenade.
 * The concept of assigning the L button to draw another type of weapon. In the beta version, the weapon was a grenade; in the final release, the weapon was a knife.
 * The 'struggle' feature where player has to break free from an enemy's grasp.
 * Leon's health indicator. It flashes when Leon is hurt, but in the final release the developers decided to add a HUD to display more information.

Development
First shown at E3 in 2003, this version was set in a mansion and featured Leon fighting what appeared to be paranormal enemies, such as medieval suits of armor and living dolls. Still infected with a virus as in "Castle", the screen would adopt a blue filter once the paranormal entities appeared as part of hallucinations. The most notable enemy in this version was the "Hook Man", a possessed-looking man carrying a large hook.

This version was reportedly so scary that Shinji Mikami warned the gamers with an infamous quote "Don't pee your pants" prior showing the initial trailer at E3. Gameplay footage of this version was featured in the Biohazard 4 Secret DVD. Ultimately, "Castle" and "Hallucination" were scrapped due to technical limitations which would cost too much to resolve.
