anyone got any tips for taking out the soldiers in the Lobby after rescuing the scientists?
I've gotten killed by the marines in this section so many times, I'm considering turning on the console and enabling God Mode.
Shoot the first few that rappel down, then immediately shoot the ones that are on the roof shooting down at you.
Then basically just hide behind the metal crates near the back and wait for them to approach you. Some of them drop medkits, so make sure to look out for them.
