These anime-like faces (caricatures of the game's developers?) can be found in the first CHR bank. It's not known whether these were meant to appear in the game somehow.

Regional Differences

Cutscenes

A couple of the game's cutscenes have changes between each version:

Japan	US

The scene following stage 6 has Reese getting shot in the head in the Japanese version. The US version simply has him getting jarred by an explosion while the background flashes, most likely due to the violence factor.

In the scene after stage 9, the close-up of Hart that follows the boss monster's transformation flashes a different color in each version.
