"Some fixes are coming for Bad Company 2 for PC, people!
Now.. we want to announce these first fixes we have made and let you know that these are just one part of a bigger list of updates that we are going to release very soon. This update will also require server downtime
This is what we can confirm for now:
One of the Insignia's requiring an unobtainable Bronze star for the tracer dart – requirement removed.
- One of the Insignia's requiring an unobtainable Bronze star for the tracer dart – requirement removed.
- Hit registration changes brought over from MOH to BC2; several bugfixes, the client<->server send rates have been increased, some of the hitboxes themselves have been changed. This will increase the accuracy of guns, but will not make much of a difference to the knife.
Removed the blue box behind the chat window.
- The 2-second immunity when spawning/being revived can will now be immediately remove either by firing, zooming, or any movement (move, crouch, jump). Merely looking around will not remove the invulnerability. In essence: If a person moves, he is never invulnerable.
- 3D vision fixed. "
