biohazard 0 TRIAL EDITION is a playable demo of Resident Evil 0 released in Japan in August 2002.[1]

Unused items

It should be noted that the can of lighter oil was used in the trial edition coding as a placeholder 3D model for unfinished models. In the table below, "No" means that the item was cut from the game before a particular image template was completed. If it lacks its own sprite or 3D model, it was cut fairly-early; conversely an item with both completed was cut not long before the game's shipping. When an item is designated "NULL", it will lack any description, including an actual name.
