Headscratchers / Critical Path

• Remember that replacement part that Kat was bringing to the helicopter? In the ending sequence, the bad guy ambushes Kat right when she reaches the helicopter, only for the player character to distact him by setting off a siren so that Kat has opportunity to shoot him. Then Kat and the player character get in the helicopter, take off, and launch a missile at the bad guy when he gets back up and tries to shoot the helicopter. It doesn't show anyone installing the replacement part in the helicopter before it takes off, nor does it seem like there would have been enough time to do so.
• Kat discovers that the main antagonist is smuggling drugs in giant metal crucifixes. Why he'd have to smuggle them, where he's smuggling them to, and what government would be left to prosecute him after most of the global population was killed is never actually brought up.
