Oblivion Lost duly became S.T.A.L.K.E.R. - Oblivion lost. A new loading screen, with the Chernobyl NPP in the background, was added. However, the splash screen with the Aztec Pyramids from build 1098 persists. Most of the weapon sounds and animations where placeholders from Counter-Strike. Just like build 1098, it was a small tech demo, featuring only 2 playable levels, 3 different NPCs, and a few weapons.
