Resident Evil 4 currently has six version of the title available, or three if you consider the PS2, PC and GC versions to be the same. Now, with the Resident Evil Project put into place the world will get to experience, arguably, most anticipated version–an HD remake of both RE: 4 and Code Veronica X. Both titles will be heading to PSN and XBLA this fall.
They will be download only versions of the games and will be the most complete renditions as well. Resident Evil 4 HD will feature the Ada Wong side mission and Code Veronica will have all the extra bits which includes glowing eyes Wesker. There isn’t much else to be said about the releases as you have likely already made up your mind whether you will buy the games or not just from the title.
Here is an image to show the side-by-side comparison of the original and the HD version. The difference is drastic.
