The article argues that Metal Gear Solid 4 effectively ignored a major technology introduced in Metal Gear Solid 2: Ocelot’s portable device that could deflect and disable projectiles. This matters because MGS4 centres on control of the world’s weapons systems, yet the earlier device would appear to make conventional weapons largely obsolete, creating a significant inconsistency in the series’ plot.

The device was initially used to explain Fortune’s apparent invulnerability in MGS2, although she later seems to reproduce its effects without a clear explanation. The writer suggests it served Fortune’s personal storyline more than the wider narrative, while MGS4 later attributed characters’ unusual abilities to nanomachines. Despite the apparent retcon, the article says fans have largely overlooked it amid the series’ many other elaborate plot developments.
