Continuity mistake: Snow and Emilie find the inmates used in experiments. Then Alex and a couple of others get the jump on them and they have a fight. Snow grabs his gun and gets shot at, and falls down the elevator shaft. He lands and is knocked out, with his left arm draped over himself across his chest as he lies partly on his side. The next time he is shown moments later, he is now flat on his back with both arms at his sides. (01:11:35)
Plot hole: The security measures for the prison depicted in this film are completely ridiculous. Not only are the prisoners confined to one central area and greatly outnumber the guards, but the cryostasis cells the prisoners are kept in are designed in such a way that the prisoners are able to simply step out and easily overwhelm the guards when the doors are opened, with the prison's backup plan being to release sleeping gas in the area to regain control. If the prison was so concerned about having to go the measure of using sleeping gas to control the situation, then surely they could have simply designed the cryostasis cells to have the prisoners restrained as a fail safe in the event that they are all simultaneously released without authorization in order to prevent the prisoners from overrunning the prison as easily as they are depicted doing. Since the prisoners are being kept in cryosleep, there is no reason to not have them restrained, because they have no need to move around. For a prison that is repeatedly described as being maximum security, it sure has some glaring weaknesses. (00:13:30 - 00:18:45)
[Alex shoots an engineer.]
Alex: Hopefully this will short circut me the inevitable "it can't be done" discussion. I need this door open, now.
Chosen answer: They are in a space station prison. Most likely the bullet from the gun hit an oxygen tank or line and caused a spark. Pure oxygen is highly explosive.
