Last detection?

[useristaken]

When was L4D2 and TF2 last detections?
I'd like to know.

Also...do I need to disable anything in my BIOS, use this cheat in a USB or something like that? Some providers will tell you to take some steps before launching the cheat.

Regards.

L4D2 has never been detected and it's been years since TF2 has been, bios changing and loader on a USB is only required for CSGO and H1Z1.
