Version 1.2
1.2 Patch: mw3v12.exe (6,187 KB)

With this latest patch there still are rare occurrences during a Multiplayer game when one player is not seen by other players. This is fixed by exiting the session that you are playing and restarting again.


The following problems have been fixed in version 1.2:
  • If 8MB 3-D textures are selected, the program no longer crashes after several waves of Instant Action.
  • The crackling and popping sounds heard on PCI sound cards (such as the Sound Blaster Live! and Sound Blaster PCI 128 sound cards) have been eliminated.
  • The Cauldron Born, Puma, Supernova and Vulture configurations now include Double Heat Sinks instead of regular Heat Sinks.
  • If the control setup has been customized, installing the update will no longer reset the controls to Joystick/Keyboard.
The following multiplayer changes have been made in version 1.2:
  • Your BattleMech's arms will no longer "flail" around on the other players' screens.
  • Your 'Mech will no longer "run in place" on other players' screens.
  • If you quickly type uppercase letters and question marks in the multiplayer chat window, the program no longer crashes.
  • Weapon groupings are saved after a player dies and respawns.
The following enhancements have been made in version 1.2:
  • The ability to add maps has been implemented. New maps will be periodically made available for download from our Web site.
  • Multiplayer lag and packet loss have been significantly reduced.
  • Reporting of team scores is now possible on the MSN Gaming Zone.
  • Two new multiplayer maps, Durgan City and The Spaceport, have been added.
  • You can now enter IP addresses using the numeric keypad.
