Longtime fans of Resident Evil will know of Resident Evil 1.5 as the near completed Resident Evil 2 that Capcom decided to can as they explored a completely different story in what was to be the actual Resident Evil 2.
Now, a group of modders have come across the code as they attempt to complete the work and release Resident Evil 1.5 to the world. As someone attempted to sell the unfinished code on Ebay the group decided to release an unfinished version (in order to thwart any attempts to make a profit off the unfinished game) - beware, though the released ISO is far from complete and is not very stabile.
