Other mistake: Bright realises that the door is unlocked as he pounds on it. The sliding door opens just a little, and the power is off, so it is implied and shown initially that they can be moved by hand. However when they go out of the room and when they go free Sayla and the others, it looks like the door are opening by themselves, not slid open by hand. (00:12:30)

1 other mistake in Escape from Luna II - chronological order
Starring: Michael Kopsa, Alaina Burnett, Chris Kalhoon
Plot hole: Char is able to escape from Side 7 simply flipping a couple grenades he had on his person (shaped like the old style pineapple grenades) who tear huge holes into metal walls with a visible thickness in excess of a meter, including the outer wall of the space colony a salvo of Mega Particle Cannon from the battleship didn't break. If Zeon has such explosives at their disposal, then maybe they should not fight with battleships and giant robots, but simply have footsoldiers toss tiny grenades at the enemy. (00:15:00)
