Need to give the user, unlimited potential to save their own progress on their own during campaign mode.
I have noticed during Chapter 1 and Chapter 2, that you try to command the Terminator to leave Defend Mode and then Follow near a door that you have closed, sometimes he will be disobedient, and not follow orders, but remains behind in front of the door, that you just closed.
On easy mode, it has collapsed three to four times during Chapter 2 during a heavy Genestealer onslaught during trying to shut down the systems to prevent more Genestealers from coming out and over running the Squad.
