As part of their continuous support, Bohemia Interactive has released a new patch for its award-winning tactical military shooter, Arma 2. Patch 1.62 brings a lot of fixes to multiplayer, which – aside for the large scale military battles – will also make zombie hunts much less prone to crashes and should improve server stability. The other highlights of version 1.62 are:
• Multiplayer optimizations, security and server improvements
  
• Overall stability was improved with numerous tweaks and fixes
  
• Added new video options (Post-Process Anti-Aliasing, Alpha To Coverage)
  
• Additional AI improvements and numerous bug fixes
  
• Resolved issues with several training missions
  
• Added a lot of new script commands for content makers

For the full list of fixes, be sure to check out 1.62’s readme file, which is provided together with the .exe file.
