Today's update is mostly balance-related gameplay changes, but also includes some UI and bug fixes. [b]Gameplay Changes[/b] [list] [*] Rebalanced a bunch of missions that our metrics indicated were abnormally difficult. [*] Increased the base health of "proper tanks" like the M60 and M1 from 3 to 4 so that they're slightly more survivable. They will still become immobilized when reduced to 1 health. [*] Increased the damage of the M67 used by enemy anti-tank teams from 2-5 to 2-6 to match the increase in tank health. [*] Added the ability for utility helicopters (UH-1, UH-4) to fire their door guns while flying and after landing. [*] Added an ammo count to mortar teams (6 rounds). [*] Added an ability to M813 cargo trucks that resupplies ammo to friendly infantry units. [*] Adjusted the AI to be more defensive on SAM hunt and convoy missions. [*] Improved the AI's ability to advance with infantry. [/list] [b]UI Changes[/b] [list] [*] Improved the instructions for the first tutorial, hopefully... [*] Adjusted the hotkeys for abilities to be more consistent between units. [/list] [b]Bug Fixes[/b] [list] [*] Fixed a crash when starting the game without an enabled audio device. [*] Fixed a bug where artillery that missed but landed on a unit outside of your vision would not play an explosion animation. [*] Fixed a bug where recon teams did not show attack previews for designating airstrikes. [*] Fixed a bug where M664 sentry turrets and would provide vision for enemy artillery. [/list]
