Right after the engine room where you obtain the "singularity core" you come to a brute, who kills Hammond (Owned?) and then after this encounter, you're heading back to the tram. On the way you come to a room where you need one of those battery things to unlock doors. However, there doesnt seem to be one anywhere among the room. I've heard people have had problems with this before but I want to know how to fix it.
If this is due to a glitch or something wrong with the game, I think EA will need to send out an apology, 'coz to get to chapter 9 from the start again will actually take the ****.
