Game mechanics:
- Squadron players are now matched only against other squadrons, as a separate game mode. This was done because of a widespread discontent with the balance.
- Account registration window has been redesigned. Password strength indication added. User consent dialog moved to the signup step. A new flow specific to South Korea was introduced to match regulations there.
Graphics:
- Improved airplane user interface. Horizon bar added. The HUD itself is now projected in front of the aircraft.
- Overhauled camera position for all aircraft carriers. The new angle looks better in battle.
- Added marker lights with different colors for MQ-20 and AH-64 Apache. (more units will make use of them in the future)
- Bubble effect added for torpedoes and submarine propellers.
- New sea bottom textures.
Optimization:
- Projectile effects optimized for a smoother battle experience.
Bug fixes:
- Fixed missing loading indication during registration by e-mail.
- Disallowed new account passwords that contain only whitespaces.
- Fixed the situation when more than 3 aircraft could be present in a squad.
- The blacklist now shows the updated names of the players.
- Fixed wrong ship type displayed on the radar when using RF Project 2145.
- Fixed RF Yuriy Dolgorukiy missile shafts not opening fully visually.
- Corrected the amount of bombers in aircraft carrier descriptions.
- Fixed the bug when upgrading Type 004 anti-air would hide the name of the weapon.
- Fixed the crash when one attempted to sign in with Facebook more than once.
- Fixed minor mistakes in several localizations.
- Fixed the voice over announcing the wrong steering direction. (“turn left” when it should be “right”)
- Corrected the loading screen inside inbox menu.
Tank mode:
- We are shifting our focus towards the tank mode, which is frankly a gargantuan task. But more and more developers are getting involved, as we know we are expected to deliver something special. So stay tuned.
