The SecuROM implemented with Battlefield: Bad Company 2 has been explained a bit by DICE over on the official blog, and it looks like it will only be running when the game is running.
The version is a wrapper around the main game executable. It does everything it can by running as a “normal” program; it does not install any sort of kernel software.
- No software is permanently installed on your machine.
- SecuROM is ONLY running when the game is running
- When you uninstall the game, you will also uninstall the SecuROM software.
Authentication: You can authenticate by putting the DVD in the drive.
If you choose this method, you must have the DVD available every time you want to play. With this method, SecuROM will not go online at all. You can then play the single-player campaign 100 percent offline.
Authentication by going online: You can also choose to authenticate by going online once
When you purchase the game, you can authenticate it on up to 10 or 11 machines (1 DVD + 10 online). This allows you to play the single-player campaign on several machines at the same time.
Not too bad, really, considering some options for PC games of late.
SecuRom methods have been in the news quite a bit lately, what with Ubisoft changing its method, and GFWL limiting the number of activations for BioShock 2 despite its version of the detection software being used as a system check only.
BFBC2 is out in March.
